Exploring Headaches in Pediatric Behçet Disease: Prevalence, Clinical Impact, and Management.

Behçet's Disease (BD), also recognized as Behçet Syndrome, manifests uniquely in pediatric populations as Pediatric Behçet's Disease (PBD), characterized by multisystemic inflammatory symptoms including recurrent oral and genital aphthae, and diverse ocular, vascular, and neurological involvements. This review elucidates the prevalence, burden, and management strategies of headaches in children with PBD, focusing on both primary headaches, such as migraine and tension-type headaches, and secondary headaches linked to systemic disease manifestations. It explores the pathophysiological underpinnings specific to PBD-related headaches and discusses the intricate relationship between systemic inflammatory processes and neurological symptoms. By examining the literature from 2004 to 2024, this study highlights the high frequency of headache in PBD patients, underscoring its diagnostic and clinical significance. We aim to provide a detailed understanding of headache management in PBD, emphasizing tailored therapeutic strategies that address the unique challenges faced by this patient population. This review also underscores the importance of comprehensive clinical evaluations to optimize outcomes and mitigate long-term sequelae, proposing that awareness and understanding of headache in PBD can significantly enhance both diagnosis and management.

Evolution of threat response-related polymorphisms at the SLC6A4 locus in callitrichid primates.

Variation in an upstream repetitive region at the SLC6A4 locus, which encodes the serotonin transporter, is associated with anxiety-related behaviour in a few primate species, including humans and rhesus macaques, and has been suggested to be related to ecological adaptability among macaques. In this study, we investigate evolution of SLC6A4 polymorphisms associated with anxiety-related behaviour in common marmosets (Callithrix jacchus). Assaying variation in the SLC6A4 repeat region across 14 species in eight genera of callitrichid primates (marmosets and tamarins), we find large interspecific variation in the number of repeats present (24-43). The black tufted-ear marmoset (C. penicillata) has sequence polymorphisms similar to those found in the common marmoset, which is its sister species, and no other species has intraspecific variation at these sites. We conclude that, similar to humans and macaques, the functional polymorphism at SLC6A4 in common marmosets has a recent evolutionary origin, and that the anxiety-related allele is evolutionarily derived. Common/black tufted-ear marmosets and rhesus/bonnet macaques share high ecological adaptability and behavioural flexibility that we propose may be related to the maintenance of the polymorphism.

The Role of the Autonomic Nervous System in Epilepsy and Migraine: A Narrative Review.

Autonomic symptoms may be local and general clinical manifestations of both epilepsy and migraine caused by the dysfunction of brain areas best known as the central autonomic network. Despite their prevalence, autonomic signs are often misdiagnosed and their treatment is undervalued. This review aims to describe the autonomic manifestations reported during seizures and migraineur attacks according to their presentation, focusing on the role of the central autonomic network (CAN) and on the parasympathetic outflow that often-induced cranial autonomic symptoms (CAS) during migraineur attacks. Further, our purpose is to analyze the pathophysiological meanings and whether their presence influences the prognosis and therapy of these disorders.

Novel causative variants in Legius syndrome: SPRED1 Genotype spectrum expansion.

Legius syndrome, commonly referred to as SPRED1-related neurofibromatosis type 1-like syndrome, is a rare autosomal dominant disorder characterized by café-au-lait macules, freckling, lipomas, macrocephaly, and heterogeneous neurodevelopmental manifestations, including a different degree of learning difficulties. Although a partial clinical overlap exists with neurofibromatosis type 1 (NF1), Legius syndrome is distinguished by its genetic etiology and the absence of neurofibromas, indicating an inherent lack of tumor risk. The SPRED1 gene encodes the Sprouty-related protein with an EVH1 domain 1 (SPRED1), a negative regulator of the RAS-MAPK signaling pathway with a crucial role in cellular growth and development. Despite various genetic variants and genomic deletions associated with Legius syndrome, the full genetic spectrum of this condition remains elusive. In this study, we investigated the underlying genetic etiology in a cohort of patients presenting with typical manifestations of Legius syndrome using a custom Next Generation Sequencing (NGS) panel and Multiplex Ligation-Dependent Probe Amplification (MLPA) for NF1 and SPRED1. We identified 12 novel SPRED1 damaging variants segregating with the phenotype in all families. These rare variants affect conserved residues of the protein and are predicted damaging according to in silico tools. No clear genotype-phenotype correlations could be observed in the current cohort and previously reported patients, underscoring the heterogeneous genotype spectrum of this condition. Our findings expand the understanding of SPRED1 variants causing Legius syndrome and underscore the importance of comprehensively characterizing the genetic landscape of this disorder. Despite the absence of clear genotype-phenotype correlations, elucidating the genetic etiology of Legius syndrome is pertinent for facilitating accurate diagnosis, genetic counseling, and therapeutic interventions.

The non-clinical burden of febrile seizures: a systematic review.

Febrile seizures (FS) can be frightening for parents, even though they are usually harmless. Various questionnaires have been used to assess parental reactions and awareness about FS, revealing insufficient knowledge. Studies have shown that educational interventions significantly reduce parental concerns, improve knowledge, and promote better first-aid measures. Providing clear information and emotional support to parents is important to reduce their concerns and improve FS management. Healthcare providers should give comprehensive information about FS, including the risk of recurrence, and provide clear instructions on their management. The economic impact of FS includes direct and indirect costs. Studies have shown a decrease of hospitalizations and associated costs due to improved clinical adherence to guidelines, which also reduces the inappropriate use of healthcare resources. This systematic review provides a comprehensive overview of the existing literature on parental anxiety and education about FS, as well as their economic impact, aiming at identifying areas for improvement in the management of FS and providing valuable insights for healthcare providers and policymakers to better address the non-clinical burden of this condition.

Should We Rule out Celiac Disease in Recurrent Headache Disorders? A Review of the Literature.

Recurrent headaches, encompassing migraine and tension-type headaches, represent prevalent conditions affecting individuals across different age groups, exerting a substantial influence on daily functioning and quality of life. Headaches serve as common manifestations of underlying health issues. Among these, celiac disease, an autoimmune disorder activated by gluten consumption, has emerged as a noteworthy concern. Recent research indicates a correlation between celiac disease and heightened susceptibility to headaches, particularly migraines. Celiac disease (CD) is an immune-mediated systemic, widespread disorder presenting a heterogeneous constellation of symptoms with a relatively easy diagnosis and therapy. Among signs and symptoms exhibited in celiac disease patients, headache is one of the most common neurological issues addressed among both adults and children. Headache disorders and CD are highly prevalent in the general population; for this reason, any causal association between these conditions and the role of a gluten-free diet (GFD) has been debated. The aim of this manuscript is to review the current scientific literature regarding the potential association between CD and headaches and the beneficial effects of a GFD. Among the various authors, in our opinion, the current state of the evidence suggests a significant role for the early screening of CD during the initial diagnosis of recurrent headaches, either in adults or children.

An Ultra-Rare Mixed Phenotype with Combined AP-4 and ERF Mutations: The First Report in a Pediatric Patient and a Literature Review.

The adaptor protein 4 (AP-4) constitutes a conserved hetero-tetrameric complex within the family of adaptor protein (AP) complex, crucial for the signal-mediated trafficking of integral membrane proteins. Mutations affecting all subunits of the AP-4 complex have been linked to autosomal-recessive cerebral palsy and a complex hereditary spastic paraparesis (HSP) phenotype. Our report details the case of a 14-year-old boy born to consanguineous parents, presenting psychomotor delay, severe intellectual disability, microcephaly, and trigonocephaly. Despite a history of febrile seizures, subsequent years were devoid of seizures, with normal EEG. Exome sequencing revealed pathogenic variants in both the AP4B1 and ERF genes. Significantly, the patient exhibited features associated with AP4B1 mutations, including distinctive traits such as cranial malformations. The ERF gene variant, linked to craniosynostosis, likely contributes to the observed trigonocephaly. This case represents the initial documentation of a concurrent mutation in the AP4B1 and ERF genes, underscoring the critical role of exome analysis in unraveling complex phenotypes. Understanding these complex genotypes offers valuable insights into broader syndromic conditions, facilitating comprehensive patient management.

Pediatric Migraine and Visual Cortical Excitability: A Prospective Observational Study with Sound-Induced Flash Illusions.

The pathophysiological mechanisms underlying migraine are more difficult to investigate in children than in the adult population. Abnormal cortical excitability turns out to be one of the most peculiar aspects of migraine, accounting for the manifestations of migraine attacks. Recently, visual cortical excitability has been explored effectively in adult migraineurs with a technique based on cross-modal audio-visual illusions (with sound-induced flash illusions (SIFIs) being reduced in migraineurs compared to non-migraineur subjects). On such a basis, in this study, we investigated visual cortical excitability in children with migraine using SIFIs using combinations of visual and sound stimuli presented randomly. We evaluated 26 children with migraine without aura and 16 healthy children. Migraineurs did not differ from the age-matched healthy subjects regarding fission or fusion illusions but perceived more flashes in trials of multiple flashes with or without beeps. The higher number of SIFIs in migraineur children compared to adults may be due to a greater propensity of visual stimulation to be driven by auditory stimuli (i.e., acoustic dominance). The increased ability to perceive flashes reveals a hyperfunctional visual cortex, demonstrating that the use of SIFIs is a valid tool for assessing visual cortical responsiveness even in pediatric migraine.

Dermatologic Effects of Selumetinib in Pediatric Patients with Neurofibromatosis Type 1: Clinical Challenges and Therapeutic Management.

Background: Plexiform neurofibromas (pNFs) are benign neoplasms, primarily originating from Schwann cells, posing challenges in patients with type 1 neurofibromatosis (NF1) due to pain, disfigurement, compression of vital structures and potential for malignancy. Selumetinib, a MEK1/2 inhibitor, has shown promising results in treating inoperable pNFs, with clinical trials demonstrating tumor volume reduction and improved patient-reported outcomes. Despite its efficacy, dermatologic toxicities may impact the quality of life and treatment adherence. Evaluating the frequency and spectrum of such effects is crucial for effective management. Methods: In a four-year retrospective and prospective study, pediatric NF1 patients with symptomatic, inoperable plexiform neurofibromas (pNFs) were treated with selumetinib. Eligibility criteria included significant morbidity, pNF size exceeding 3 cm or surgical inoperability, and performance status >70%. Hematological, liver, lung and cardiac assessments established baseline health. Selumetinib, orally administered at 25 mg/m2 twice, was administered for two years unless a response warranting extension occurred. Cutaneous AEs were documented and graded by severity according to CTCAE v5.0, with evaluations every three to six months. The impact on symptoms and pNF size was systematically recorded, and biopsies characterized histopathological features in those patients requiring surgery. Results: Twenty patients were enrolled, with an average age at therapy initiation of 11.6 years. Cutaneous side effects were common, with all patients experiencing at least one and a median of two per patient. Xerosis, paronychia and acneiform rash were prevalent. Notably, pre-pubertal individuals were more susceptible to xerosis. Acneiform rash had a higher incidence in older patients and those with skin phototypes II and III. Successful management involved tailored approaches, such as clindamycin for acneiform rash and topical agents for paronychia. Hair abnormalities, including color changes and thinning, occurred, with female patients at higher risk for the latter. Paronychia presented challenges, necessitating various interventions, including surgical approaches. AEs led to treatment suspension in 20% of patients, with tumor rebound observed in 75%. Conclusions: According to our experience, successful management of selumetinib-induced cutaneous AEs requires tailored strategies including surgery. AEs might indirectly determine pNF regrowth due to therapy suspension. We thus emphasize the pivotal role of addressing cutaneous reactions for effective selumetinib management in pediatric patients.

Orofacial Migraine and Other Idiopathic Non-Dental Facial Pain Syndromes: A Clinical Survey of a Social Orofacial Patient Group.

Background: Orofacial pain syndromes (OFPs) are a heterogeneous group of syndromes mainly characterized by painful attacks localized in facial and oral structures. According to the International Classification of Orofacial Pain (ICOP), the last three groups (non-dental facial pain, NDFP) are cranial neuralgias, facial pain syndromes resembling primary headache syndromes, and idiopathic orofacial pain. These are often clinical challenges because the symptoms may be similar or common among different disorders. The diagnostic efforts often induce a complex diagnostic algorithm and lead to several imaging studies or specialized tests, which are not always necessary. The aim of this study was to describe the encountered difficulties by these patients during the diagnostic-therapeutic course. Methods: This study was based on the responses to a survey questionnaire, administered to an Italian Facebook Orofacial Patient Group, searching for pain characteristics and diagnostic-therapeutic care courses. The questionnaire was filled out by patients affected by orofacial pain, who were 18 years and older, using a free online tool available on tablets, smartphones, and computers. Results: The sample was composed of 320 subjects (244F/76M), subdivided by age range (18-35 ys: 17.2%; 36-55 ys: 55.0%; >55 ys 27.8%). Most of the patients were affected by OFP for more than 3 years The sample presented one OFP diagnosis in 60% of cases, more than one in 36.2% of cases, and 3.8% not classified. Trigeminal neuralgia is more represented, followed by cluster headaches and migraines. About 70% had no pain remission, showing persisting background pain (VAS median = 7); autonomic cranial signs during a pain attack ranged between 45 and 65%. About 70% of the subjects consulted at least two different specialists. Almost all received drug treatment, about 25% received four to nine drug treatments, 40% remained unsatisfied, and almost 50% received no pharmacological treatment, together with drug therapy. Conclusion: To the authors' knowledge, this is the first study on an OFP population not selected by a third-level specialized center. The authors believe this represents a realistic perspective of what orofacial pain subjects suffer during their diagnostic-therapeutic course and the medical approach often results in unsatisfactory outcomes.

The Influence of Ketogenic Diet on Gut Microbiota: Potential Benefits, Risks and Indications.

The ketogenic diet (KD) restricts carbohydrate consumption, leading to an increase in ketone bodies, such as acetoacetate, ß-hydroxybutyrate, and acetone, which are utilized as energy substrates. This dietary approach impacts several biochemical processes, resulting in improved clinical management of various disorders, particularly in childhood. However, the exact mechanisms underlying the efficacy of KD remain unclear. Interestingly, KD may also impact the gut microbiota, which plays a pivotal role in metabolism, nutrition, and the development of the immune and nervous systems. KD has gained popularity for its potential benefits in weight loss, blood sugar control, and certain neurological conditions. This narrative review sums up KD-related studies published over 30 years. While short-term studies have provided valuable insights into the effects of KD on the gut microbiota, persistent uncertainties surround its long-term efficacy and potential for inducing dysbiosis. The significant influence of KD on epigenetic mechanisms, intracellular pathways, and gut microbial composition underscores its potential as a therapeutic choice. However, a judicious consideration of the potential risks associated with the strict adherence to a low-carbohydrate, high-fat, and high-protein regimen over prolonged periods is imperative. As KDs gain popularity among the adolescent and young adult demographic for weight management, it becomes imperative to undertake additional research to comprehensively assess their impact on nutritional status and gut microbiota, ensuring a holistic and sustainable approach to medical nutrition.

Congenital Myopathy as a Phenotypic Expression of CACNA1S Gene Mutation: Case Report and Systematic Review of the Literature.

BACKGROUND: Congenital myopathies are a group of clinically, genetically, and histologically heterogeneous diseases caused by mutations in a large group of genes. One of these is CACNA1S, which is recognized as the cause of Dihydropyridine Receptor Congenital Myopathy. METHODS: To better characterize the phenotypic spectrum of CACNA1S myopathy, we conducted a systematic review of cases in the literature through three electronic databases following the PRISMA guidelines. We selected nine articles describing 23 patients with heterozygous, homozygous, or compound heterozygous mutations in CACNA1S and we added one patient with a compound heterozygous mutation in CACNA1S (c.1394-2A>G; c.1724T>C, p.L575P) followed at our Institute. We collected clinical and genetic data, muscle biopsies, and muscle MRIs when available. RESULTS: The phenotype of this myopathy is heterogeneous, ranging from more severe forms with a lethal early onset and mild-moderate forms with a better clinical course. CONCLUSIONS: Our patient presented a phenotype compatible with the mild-moderate form, although she presented peculiar features such as a short stature, myopia, mild sensorineural hearing loss, psychiatric symptoms, and posterior-anterior impairment gradient on thigh muscle MRI.

May Artificial Intelligence Influence Future Pediatric Research?-The Case of ChatGPT.

BACKGROUND: In recent months, there has been growing interest in the potential of artificial intelligence (AI) to revolutionize various aspects of medicine, including research, education, and clinical practice. ChatGPT represents a leading AI language model, with possible unpredictable effects on the quality of future medical research, including clinical decision-making, medical education, drug development, and better research outcomes. AIM AND METHODS: In this interview with ChatGPT, we explore the potential impact of AI on future pediatric research. Our discussion covers a range of topics, including the potential positive effects of AI, such as improved clinical decision-making, enhanced medical education, faster drug development, and better research outcomes. We also examine potential negative effects, such as bias and fairness concerns, safety and security issues, overreliance on technology, and ethical considerations. CONCLUSIONS: While AI continues to advance, it is crucial to remain vigilant about the possible risks and limitations of these technologies and to consider the implications of these technologies and their use in the medical field. The development of AI language models represents a significant advancement in the field of artificial intelligence and has the potential to revolutionize daily clinical practice in every branch of medicine, both surgical and clinical. Ethical and social implications must also be considered to ensure that these technologies are used in a responsible and beneficial manner.

Evolution of Pediatric Migraine Patients Admitted at an Emergency Department after a 10-Year Follow-Up.

BACKGROUND: Despite its high prevalence, the clinical course of pediatric migraine has not been fully understood, and previous studies present conflicting results. We present here the findings of a 10-year follow-up study involving children with severe migraine pain admitted to our emergency department. Furthermore, all studies were carried out on selected outpatient clinical case studies. Our aim was to evaluate a population of migraine children admitted to an emergency department because of increased severity or frequency of pain or even because of very anxious parents concerning their child's headache in order to describe their long-term outcomes, whether it differed from that of outpatient populations and to identify possible predictors of prognosis. METHODS: We recruited 80 subjects with migraine headaches (mean age 8 years with a range of 4-14 years, 50% females), attending the baseline examination of a population admitted for a headache to the Emergency Department in the first half year of 2012. Of the 80 subjects, 48 (60%) were eligible for follow-up in 2022. We included in our study only patients diagnosed with migraine, according to the diagnostic criteria of the International Classification of Headache Disorders. All were contacted by telephone, and a semi-structured questionnaire was provided to them by email. The association between several possible prognostic factors (gender, familiar neurologic disorders, prenatal and perinatal disorders, social activities, sleep disorders, etc.) and the long-term persistence of migraine headaches were explored using logistic regression analysis. RESULTS: Of 48 subjects with migraine headaches at baseline, 31 (65%) had persistent migraine, and 17 (35%) experienced remission. The preliminary results showed that the presence of neurologic disorders in parents (p < 0.01-odds ratio 9.34 (2.53-41.64) and sleep disorders (p < 0.01-odds ratio 13.18 (2.25-252.74) significantly predicted the 10-year persistence of migraine headaches, while the other considered predictors were found not to influence prognosis. CONCLUSIONS: To our knowledge, this was the first study conducted on a selected pediatric population upon admission to the emergency room. Our study suggests that a population of pediatric migraine selected for admission to the emergency department also shows a favorable long-term prognosis, like the studies conducted in the outpatient sample. Familial neurological comorbidity and sleep disorders were unfavorable factors for predicting good outcomes.

Idiopathic Non-Dental Facial Pain Syndromes in Italian Children: A Clinical Case Series.

BACKGROUND: The orofacial pain syndromes (OFPs) are a heterogeneous group of syndromes characterized by painful attacks involving the orofacial structures. They may be summarily subdivided into two great categories: (1) orofacial pain mainly attributed to dental disorders such as dentoalveolar and myofascial orofacial pain or temporomandibular joint (TM) pain; (2) orofacial pain mainly attributed to non-dental pain as neuralgias, facial localization of primary headaches or idiopathic orofacial pain. The second group is uncommon, often described by single case reports, can often show overlapping symptoms with the first group, and represents a clinical challenge, carrying the risk of undervaluation and possibly invasive odontoiatric treatment. We aimed to describe a clinical pediatric series of non-dental orofacial pain and better to underline some topographic and clinical features associated with them. We retrospectively collected the data of children admitted to our headache centers (Bari, Palermo, Torino) from 2017 to 2021. Our inclusion criterion was the presence of non-dental orofacial pain following the topographic criteria of 3° International Classification of Headache Disorders (ICHD-3), and exclusion criteria included the pain syndromes attributed to the dental disorders and pain syndromes due to the secondary etiologies Results. Our sample comprised 43 subjects (23/20 M/F, in the range of ages 5-17). We classified them int: 23 primary headaches involving the facial territory during attacks, 2 facial trigeminal autonomic cephalalgias, 1 facial primary stabbing headache, 1 facial linear headache, 6 trochlear migraines, 1 orbital migraine 3 red ear syndrome and 6 atypical facial pain. All patients described debilitating pain for intensity (moderate/severe), 31 children had episodic attacks, and 12 had continuous pain. Almost all received drugs for acute treatment (less than 50% were satisfied), and some received non-pharmacological treatment associated with drug therapy Conclusion. Although rare OFP can occur in pediatric age, it can be debilitating if unrecognized and untreated, affecting the psychophysical well-being of young patients. We highlight the specific characteristics of the disorder for a more correct and earlier identification during the diagnostic process, already difficult in pediatric age, and to define the approach and possible treatment to prevent negative outcomes in adulthood.

Chemogenetics identifies separate area 25 brain circuits involved in anhedonia and anxiety in marmosets.

Poor outcomes are common in individuals with anxiety and depression, and the brain circuits underlying symptoms and treatment responses remain elusive. To elucidate these neural circuits, experimental studies must specifically manipulate them, which is only possible in animals. Here, we used a chemogenetics strategy involving engineered designer receptors exclusively activated by designer drugs (DREADDs) to activate a region of the marmoset brain that is dysfunctional in human patients with major depressive disorder, called the subcallosal anterior cingulate cortex area 25 (scACC-25). Using this DREADDs system, we identified separate scACC-25 neural circuits that underlie specific components of anhedonia and anxiety in marmosets. Activation of the neural pathway connecting the scACC-25 to the nucleus accumbens (NAc) caused blunting of anticipatory arousal (a form of anhedonia) in marmosets in response to a reward-associated conditioned stimulus in an appetitive Pavlovian discrimination test. Separately, activation of the circuit between the scACC-25 and the amygdala increased a measure of anxiety (the threat response score) when marmosets were presented with an uncertain threat (human intruder test). Using the anhedonia data, we then showed that the fast-acting antidepressant ketamine when infused into the NAc of marmosets prevented anhedonia after scACC-25 activation for more than 1 week. These neurobiological findings provide targets that could contribute to the development of new treatment strategies.

Neurovisual Manifestations in Children with Mild COVID-19: An Association to Remember.

Neurovisual involvement has been reported in a number of patients with severe SARS-CoV-2 disease (COVID-19), mainly among adult patients. In children, such involvement has been reported in rare cases, often in those presenting with severe forms of COVID-19. The aim of this work is to explore the association between mild COVID-19 and neurovisual manifestations. We report the cases of three previously healthy children who developed neurovisual manifestations following mild acute COVID-19, analysing the clinical phenotype, the latency between the onset of acute COVID-19 and neurovisual involvement, and the kinetic of resolution. Our patients developed different clinical patterns, including visual impairment and ophthalmoplegia. In two cases, these clinical features occurred during acute COVID-19, while in the third patient their development was delayed after 10 days from disease onset. Furthermore, the dynamics of resolution were different, with one patient showing remission after 24 hours, the second after 30 days, and the third showing persistence of the strabismus after 2 months of follow-up. The spreading of COVID-19 among the paediatric population will probably lead to an increase of atypical disease forms, including those presenting with neurovisual involvement. Therefore, a better knowledge of the pathogenic and clinical features of these manifestations is warranted.

Phenotypic Spectrum of NFIA Haploinsufficiency: Two Additional Cases and Review of the Literature.

The NFIA (nuclear factor I/A) gene encodes for a transcription factor belonging to the nuclear factor I family and has key roles in various embryonic differentiation pathways. In humans, NFIA is the major contributor to the phenotypic traits of "Chromosome 1p32p31 deletion syndrome". We report on two new cases with deletions involving NFIA without any other pathogenic protein-coding gene alterations. A cohort of 24 patients with NFIA haploinsufficiency as the sole anomaly was selected by reviewing the literature and public databases in order to analyze all clinical features reported and their relative frequencies. This process was useful because it provided an overall picture of the phenotypic outcome of NFIA haploinsufficiency and helped to define a cluster of phenotypic traits that can facilitate clinicians in identifying affected patients. NFIA haploinsufficiency can be suspected by a careful observation of the dysmorphisms (macrocephaly, craniofacial, and first-finger anomalies), and this potential diagnosis is strengthened by the presence of intellectual and developmental disabilities or other neurodevelopmental disorders. Further clues of NFIA haploinsufficiency can be provided by instrumental tests such as MRI and kidney urinary tract ultrasound and confirmed by genetic testing.
