Expanded targeted preconception screening panel in Israel: findings and insights.

BACKGROUND: We aimed to analyse the efficacy and added value of a targeted Israeli expanded carrier screening panel (IL-ECSP), beyond the first-tier test covered by the Israeli Ministry of Health (IMOH) and the second-tier covered by the Health Maintenance Organisations (HMOs). METHODS: A curated variant-based IL-ECSP, tailored to the uniquely diverse Israeli population, was offered at two tertiary hospitals and a major genetics laboratory. The panel includes 1487 variants in 357 autosomal recessive and X-linked genes. RESULTS: We analysed 10 115 Israeli samples during an 18-month period. Of these, 6036 (59.7%) were tested as couples and 4079 (40.3%) were singles. Carriers were most frequently identified with mutations in the following genes: GJB2/GJB6 (1:22 allele frequency), CFTR (1:28), GBA (1:34), TYR (1:39), PAH (1:50), SMN1 (1:52) and HEXA (1:56). Of 3018 couples tested, 753 (25%) had no findings, in 1464 (48.5%) only one partner was a carrier, and in 733 (24.3%) both were carriers of different diseases. We identified 79 (2.6%) at-risk couples, where both partners are carriers of the same autosomal recessive condition, or the female carries an X-linked disease. Importantly, 48.1% of these would not have been detected by ethnically-based screening tests currently provided by the IMOH and HMOs, for example, variants in GBA, TYR, PAH and GJB2/GJB6. CONCLUSION: This is the largest cohort of targeted ECSP testing, tailored to the diverse Israeli population. The IL-ECSP expands the identification of couples at risk and empowers their reproductive choices. We recommend endorsing an expanded targeted panel to the National Genetic Carrier Screening programme.

Clinical phenotype of FOXP1 syndrome: parent-reported medical signs and symptoms in 40 individuals.

BACKGROUND: The first studies on patients with forkhead-box protein P1 (FOXP1) syndrome reported associated global neurodevelopmental delay, autism symptomatology, dysmorphic features and cardiac and urogenital malformations. The aim of this study was to assess the prevalence of congenital abnormalities in an unbiased cohort of patients with FOXP1 syndrome and to document rare complications. METHODS: Patients with FOXP1 syndrome were included, mostly diagnosed via whole-exome sequencing for neurodevelopmental delay. A parent-report questionnaire was used to assess medical signs and symptoms, including questions about features rated as most burdensome by patients and their family. RESULTS: Forty individuals were included, 20 females and 20 males. The mean age at assessment was 13.2 years (median 8.5 years; range 2-54 years; ≥18 years n = 7). Seven adults were included. All patients had developmental problems, including cognitive, communication, social-emotional and motor delays. The most prevalent medical signs and symptoms include delayed bladder control, sleeping problems, hypermetropia, strabismus, sacral dimple, undescended testes, abnormal muscle tone and airway infections. The most burdensome complaints for patients with FOXP1 syndrome, as perceived by parents, include intellectual disability, impaired communication, behaviour problems, lack of age-appropriate self-reliance, attention problems and anxiety. According to parents, patients have quite similar reported symptoms, although incontinence, obsessions and a complex sensory profile have a higher ranking. CONCLUSION: The results of this study may be used to further guide medical management and identify patient priorities for future research targeted on those features of FOXP1 syndrome that most impair quality of life of patients and their families.

Carriers of autosomal recessive conditions: are they really 'unaffected?'

Mendel's Law of Dominance suggests that recessive disease expression requires the inheritance of two mutated alleles as the dominant, wildtype allele suppresses disease presentation leading to the expression of physiological normal phenotypes. However, there is existing evidence that challenges this school of thought. Here, we summarise existing literature evaluating metabolic and health impacts among carriers of autosomal recessive conditions, focusing on phenylketonuria (PKU), classical homocystinuria, galactosemia and Usher syndrome as examples. Our findings suggest that carriers, often described as 'unaffected', may actually display attenuated symptoms for the recessive disease they are carrying. For instance, PKU is an inborn error of metabolism characterised by the build-up of plasma phenylalanine attributed to the deficiency of the phenylalanine hydroxylase (PAH) enzyme. While less severe, PKU carriers also exhibit this impaired enzymatic activity, leading to elevated plasma phenylalanine levels, especially after phenylalanine consumption. Related to these metabolic alterations in the PAH pathway, there is early evidence to suggest that PKU carriers may have compromised cognitive and mental health outcomes. Overall, research on the health and metabolic impacts of PKU carriers is sparse, with most studies conducted several decades ago. However, early evidence suggests that intermediate phenotypes among carriers of autosomal recessive conditions are plausible. The illustrated possible intermediate phenotypes observed among carriers necessitates future research to determine possible clinical implications among this population.

Two Angelman families with unusually advanced neurodevelopment carry a start codon variant in the most highly expressed UBE3A isoform.

We present three children from two unrelated families with Angelman syndrome (AS) whose developmental skills are far more advanced than any other non-mosaic AS individual ever reported. All have normal gait and use syntactic language spontaneously to express their needs. All of them have a c.2T > C (p.Met1Thr) variant in UBE3A, which abrogates the start codon of isoform 1, but not of isoforms 2 and 3. This variant was maternally inherited in one set of siblings, but de novo in the other child from the unrelated family. This report underscores the importance of considering AS in the differential diagnosis even in the presence of syntactic speech.

A randomized controlled trial of levodopa in patients with Angelman syndrome.

Treatment for Angelman syndrome (AS) is currently limited to symptomatic interventions. A mouse model of AS has reduced calcium/calmodulin-dependent kinase II activity due to excessive phosphorylation of specific threonine residues, leading to diminished long-term potentiation. In a rat model of Parkinson disease, levodopa reduced phosphorylation of various proteins, including calcium/calmodulin-dependent kinase II. Further studies demonstrated that AS mice treated with levodopa performed better on rotarod testing than untreated AS mice. We conducted a multi-center double-blind randomized placebo-controlled 1-year trial of levodopa / carbidopa with either 10 or 15 mg/kg/day of levodopa in children with AS. The outcome of this intervention was assessed using either the Bayley Scales of Infant Development or the Mullen Scales of Early Learning, as well as the Vineland Adaptive Behavior Scales, and the Aberrant Behavior Checklist. Of the 78 participants enrolled, 67 participants received study medication (33 on levodopa, 34 on placebo), and 55 participants (29 on levodopa, 26 on placebo) completed the 1-year study. There were no clinically or statistically significant changes in any of the outcome measures over a 1-year period comparing the levodopa and placebo groups. The number of adverse events reported, including the more serious adverse events, was similar in both groups, but none were related to treatment with levodopa. Our data demonstrate that levodopa is well-tolerated by children with AS. However, in the doses used in this study, it failed to improve their neurodevelopment or behavioral outcome.

Autoimmune and Inflammatory Manifestations in 247 Patients with Primary Immunodeficiency-a Report from the Slovenian National Registry.

An abnormal regulation of immune responses leads to autoimmune and inflammatory manifestations in patients with primary immunodeficiencies (PIDs). The objective of our study was to evaluate the frequency of non-infectious and non-malignant manifestations in a large cohort of patients included in the Slovenian national PID registry and to assess the time of manifestation onset with respect to the time of PID diagnosis. Medical records of registered patients were reviewed. Data on autoimmunity, lymphoproliferation, autoinflammation, allergies, PID diagnosis, and underlying genetic defects were collected and analyzed. The time of each manifestation onset was determined and compared with the time of PID diagnosis. As of May 2015, 247 patients with 50 different PIDs were registered in the Slovenian national PID registry (147 males, 100 females; mean age 20 years). Mean disease duration was 14 years; 78 % of patients were younger than 18 years; and 22 % of patients were adults. Diagnosis of PID was genetically confirmed in 51 % of patients. Non-infectious and non-malignant manifestations were present in 69/235 (29 %) patients, including autoimmune manifestations in 52/235 (22 %), lymphoproliferative/granulomatous in 28/235 (12 %), autoinflammatory in 12/247 (5 %), and allergic manifestations in 10/235 (4 %) of all registered patients. Autoimmune manifestations were present in all patients whose PIDs were classified as diseases of immune dysregulation, 47 % of patients with chronic granulomatous disease, and 38 % of patients with predominantly antibody immune deficiencies. A high prevalence of non-infectious and non-malignant manifestations among patients in the Slovenian national PID registry suggests common genetic factors of autoimmunity, inflammation, and immunodeficiency. Patients with PID should be routinely screened for autoimmune and inflammatory manifestations at the time of PID diagnosis and during the long-term follow up.

[Acute hepatic porphyrias]. / Akute hepatische Porphyrien.

Acute porphyrias are caused by rare hereditary disorders of hepatic heme biosynthesis. Episodes of accumulating neurotoxic metabolites lead to multisystemic symptoms such as visceral pain, autonomic dysregulation, neurocognitive impairment, hyponatremia, and occasionally motor paralysis. In addition to protracted non-emergency courses, acute life-threatening crises can occur, often triggered by infection, medication, fasting, or hormonal stimuli. Since the clinical presentation is nonspecific and multifaceted, many patients have gone through a long odyssey until they receive a diagnosis. Acute attacks often lead to presenting initially to the emergency department, where acute hepatic porphyria (AHP) is easily overlooked in the differential diagnosis. Establishing the diagnosis requires a high level of genuine suspicion (e.g., cluster of signs and symptoms along with certain patterns of health care resource utilization). The initial diagnostic work-up requires the measurement of metabolites in the urine. Emergency management consists of infusions of glucose and heme arginate along with symptomatic therapy. However, porphyrinogenic agents must be strictly avoided ( www.drugs-porphyria.org ). After initial diagnosis, a thorough work-up should be done at a porphyria center (confirming the diagnosis, education, genetic counselling) and issuance of an emergency identification card is mandatory. If the frequency of relapses is high, new targeted prophylactic therapies have proven effective. Patients with known porphyria require special attention in any acute medical condition in order to avoid porphyrinogenic triggers and to exclude threatening differential diagnosis (e.g., sepsis) by consistent basic diagnostics.

Alagille syndrome: an orphan disease in Colombia and summary of recent advances in treatment and survival - a case report.

Alagille syndrome has been described as a multisystemic clinical spectrum caused by an autosomal dominant genetic disorder. Although it is estimated that there is 1 case per 100 000 live births, the prognosis for survival and quality of life for these patients is varied but tends to be negative. In Colombia, this condition is considered an orphan disease with difficult management due to the lack of specialized centers that have all the medical specialties and subspecialties. Some reports state that no more than 30 cases have been published in this country. Materials and methods: The authors report a case of a male baby who, at 8 days old, he was taken to the general practitioner's outpatient clinic for persistent jaundice. At 3 months of age, he was reviewed by the pediatric gastroenterology department, which requested liver and biliary tract scintigraphy, showing atresia of the biliary tract, hepatomegaly, and the absence of a gallbladder. Results: Liver transplantation is the definitive solution. However, in low- and middle-income countries, where there are no well-established organ transplantation programs, the prognosis for these patients is presumed to be worse. Conclusion: Alagille syndrome is a rare disease that requires an accurate and early diagnosis and timely multidisciplinary management to reduce the impact of multisystemic complications. It is necessary to advance in transplant programs in low- and middle-income countries, to provide a solution to cases where there are no other therapeutic alternatives, and to contribute to the quality of life of the affected patient.

Rare genetic causes of meningitis and encephalitis.

Differential diagnosis of meningitis and encephalitis is often very challenging because it cannot be determined based on symptoms, and the diseases have various causes. This article explains rare genetic causes of meningitis and encephalitis. Autoinflammatory disorders include cryopyrin-associated periodic syndromes, familial Mediterranean fever, and tumor necrosis factor receptor-associated periodic syndrome. Furthermore, other genetic disorders, such as complement factor I deficiency, phosphatidylinositol glycan anchor biosynthesis class T mutation, and neuronal intranuclear inclusion disease, can present as meningitis and encephalitis.

Arrhythmia prevalence and sudden death risk in adults with the m.3243A>G mitochondrial disorder.

AIMS: To define the prevalence of non-sustained tachyarrhythmias and bradyarrhythmias in patients with the m.3243A>G mitochondrial genotype and a previously defined, profile, associated with 'high sudden-death risk'. METHODS AND RESULTS: Patients at high risk of sudden death because of combinations of ventricular hypertrophy, mitochondrial encephalopathy, lactic acidosis and stroke-like episodes family phenotype, epilepsy or high mutation load, due to the m.3243A>G mutation, were identified from a mitochondrial cohort of 209 patients. All recruited had serial ECG and echo assessments previously according to schedule, had an ECG-loop recorder implanted and were followed for as long as the device allowed. Devices were programmed to detect non-sustained brady- or tachy-arrhythmias. This provided comprehensive rhythm surveillance and automatic downloads of all detections to a monitoring station for cardiology interpretation. Those with sinus tachycardia were treated with beta-blockers and those with ventricular hypertrophy received a beta-blocker and ACE-inhibitor combination.Nine consecutive patients, approached (37.2±3.9 years, seven males) and consented, were recruited. None died and no arrhythmias longer than 30s duration occurred during 3-year follow-up. Three patients reported palpitations but ECGs correlated with sinus rhythm. One manifest physiological, sinus pauses >3.5 s during sleep and another had one asymptomatic episode of non-sustained ventricular tachycardia. CONCLUSIONS: Despite 'high-risk' features for sudden death, those studied had negligible prevalence of arrhythmias over prolonged follow-up. By implication, the myocardium in this genotype is not primarily arrhythmogenic. Arrhythmias may not explain sudden death in patients without Wolff-Parkinson-White or abnormal atrioventricular conduction or, it must require a confluence of other, dynamic, proarrhythmic factors to trigger them.

Nutrition rehabilitation-related complications in primary mitochondrial disorders.

Primary mitochondrial disorders (PMDs) comprise a group of hundreds of individual genetic diseases affecting mitochondrial function, including oxidative phosphorylation and energy production. The estimated prevalence of these disorders ranges from 2.9 to 20 cases per 100,000. PMDs are commonly associated with malnutrition and growth failure. There is a paucity of literature regarding nutrition assessment and long-term data in the PMD population. We present three patients with various PMDs who presented complications related to malnutrition: (1) a 16-year-old male with Kearns-Sayre syndrome developed type 2 insulin-requiring diabetes mellitus after the initiation of high-calorie nutrition rehabilitation via gastrostomy tube (G-tube); (2) an 11-year-old female with myoclonic epilepsy associated with ragged red fibers developed diarrhea with metabolic decompensation and profound neurological and respiratory deterioration during nutrition rehabilitation after surgical G-tube placement; and (3) a 19-year-old male with a WARS2-associated PMD manifesting with developmental delay and severe parkinsonism presented complications related to poor wound healing after gastrojejunostomy tube placement. The last patient required prolonged hospitalization in the intensive care unit. Clinicians should be vigilant in monitoring these possible complications, as no standards of care exist for the initiation of enteral nutrition for this unique population.

TUBGCP4 - associated microcephaly and chorioretinopathy.

Background Microcephaly and chorioretinopathy (MCCRP) is a rare neuro-ophthalmologic disorder that causes microcephaly and chorioretinopathy. In a recessive inheritance pattern, there are three types: MCCRP1; MCCRP2 and MCCRP3. MCCRP3 results from pathogenic variants in the tubulin-gamma complex-associated protein 4 (TUBGCP4) gene.Materials and Methods This is a case report of a patient with a molecular diagnosis defined by mutations in the TUBGCP4 gene. Segregation analyses were carried out.Results The molecular investigation found two heterozygous variants c.1380 G > A (p.Trp460*) a novel nonsense variant, and c.1746 G > T (p Leu582=) a synonymous variant in TUBGCP4. The clinical phenotype was characterized by microcephaly, microphthalmia, chorioretinopathy, a punched-out retinal appearance, dysmorphic facial features, decreased visual acuity, and learning difficulties. The clinical features were similar to those described previously in children with MCCRP3. The proband also had additional features including centripetal obesity, stretch marks, acanthosis nigricans, scoliosis, and hypercholesterolemia. These other features could be part of a ciliopathy syndrome.Conclusions MCCRP2 caused by pathogenic variants in PLK4 is well established as a ciliopathy disease. The role of TUBGCP4 is not well established in the cilium physiology. MCCRP3 may be part of the ciliopathy spectrum.

Screening for Carpal Tunnel Syndrome in Patients With Mucopolysaccharidosis.

Mucopolysaccharidoses (MPSs) are a group of rare lysosomal storage diseases with multisystem manifestations, including carpal tunnel syndrome (CTS). This study comprised a systematic review of literature and hospital guidelines addressing the method and frequency of screening for carpal tunnel syndrome in mucopolysaccharidosis patients and a review of carpal tunnel syndrome in patients seen in the multidisciplinary mucopolysaccharidosis clinic of a pediatric hospital, in order to develop screening recommendations. The literature reported the importance of routine carpal tunnel syndrome screening from early childhood in patients with mucopolysaccharidosis I, II, IV, and VI. Screening methods included physical examination, nerve conduction studies, electromyography, and ultrasonography. Ten of 20 mucopolysaccharidosis patients in our series underwent carpal tunnel syndrome surgery. Given the high incidence of carpal tunnel syndrome at a young age in mucopolysaccharidosis, the authors recommend performing physical examination and obtaining patient and caregiver history for carpal tunnel syndrome every 6 months from the time of mucopolysaccharidosis diagnosis, supplemented by annual nerve conduction studies in cases with poor history or equivocal examination.

Flash Pulmonary Edema: A Case and Review of Left Ventricular Non-Compaction Cardiomyopathy.

Description Left ventricular non-compaction cardiomyopathy is an uncommon type of cardiomyopathy caused by malformation of the myocardium during embryogenesis. This results in trabeculations within the ventricular wall that can affect the left and, less commonly, right ventricles. Presentation ranges from clinically asymptomatic to life-threatening arrhythmias. It is a rare and relatively unknown form of cardiomyopathy, though thought to be underdiagnosed. Prevalence is increasing due to improvements in imaging and awareness. Management is similar to that of other cardiomyopathies including angiotensin-converting-enzyme inhibitors or angiotensin receptor blockers, beta-blockers, diuretics, automatic implantable cardioverter defibrillator placement and cardiac transplantation. We present a case of a 38-year-old, otherwise healthy, Indian male who presented with flash pulmonary edema and was found to have left ventricular non-compaction cardiomyopathy. This report includes a review of left ventricular non-compaction cardiomyopathy.

Data highlighting effects of Ketogenic diet on cardiomyopathy and hepatopathy in Glycogen storage disease Type IIIA.

Datasets highlighting effects of ketogenic diet (KD) in a glycogen storage disease type IIIa patient is presented with the longest patient follow up report to date. Now a 15-year old girl with GSD type IIIa, diagnosed at 1 year of age, had initially introduced treatment with diet high carbohydrates, according to the recommendations. Progressively she developed left ventricular obstructive hypertrophy, hepatomegaly and skeletal myopathy. At the age of 11 years, she was introduced KD and continuous ketosis has been maintained for over 4 years providing longest reported follow up to date. KD introduction lead to a normalization of left ventricular parameters and ventricular mass and to an improvement in hepatic injury markers and decrease in liver size. We provided a table with biochemical parameters, a table providing detailed diet composition, tables with cardiac and hepatic measures and figures depicting cardiac NMR images; all the tables/figures are provided referring to the KD introduction (values prior/after). Interpretation of this data can be found in a case report article titled "Normalization of obstructive cardiomyopathy and improvement of hepatopathy on ketogenic diet in patient with glycogen storage disease (GSD) type IIIa".

Pediatric Palliative Care for Children with Progressive Non-Malignant Diseases.

A substantial number of children cared for by pediatric palliative care physicians have progressive non-malignant conditions. Some elements of their care overlap with care for children with cancer while other elements, especially prognosis and trajectory, have nuanced differences. This article reviews the population, physical-emotional and social concerns, and trajectory.

Aesthetic Facial Correction of Cleidocranial Dysplasia.

We report two cases of cleidocranial dysplasia, which was managed without significant craniofacial osteotomy. A mother and daughter, both of normal intelligence, presented with central forehead depression, mid-face hypoplasia, and blepharoptosis. The fact that they have an identically deformed face implied a genetic basis. In both patients, radiologic evaluation revealed the underdeveloped maxilla, persistent fontanelle opening, and cleidal aplasia. Clinical findings and radiologic studies were consistent with the diagnosis of cleidocranial dysplasia. Both patients underwent forehead plasty via bicoronal approach, augmentation rhinoplasty using tip plasty, and epicanthoplasty. In addition, the mother underwent malar augmentation using Medpor implantation and reduction genioplasty. The patients did not experience any postoperative complication and remained satisfied with the operation at 6-year follow-up.

Decreased Aerobic Capacity in ANO5-Muscular Dystrophy.

BACKGROUND: Anoctaminopathies are muscle diseases caused by recessive mutations in the ANO5 gene. The effects of anoctaminopathy on oxidative capacity have not previously been studied in a controlled setting. OBJECTIVE: To characterize oxidative capacity in a clinically and genetically well-defined series of patients with anoctaminopathy. METHODS: We sequenced the ANO5 gene in 111 Finnish patients with suspected LGMD2. Patients with positive findings underwent close clinical examination, including electromyography, muscle MRI, and, in selected cases, muscle biopsy. Oxidative capacity was analyzed using spiroergometry and compared to age-matched healthy controls. RESULTS: We characterized 12 newly identified and 2 previously identified patients with ANO5 mutations from 11 families. Our material was genetically homogeneous with most patients homozygous for the Finnish founder variant c.2272C>T (p.Arg758Cys). In one family, we found a novel p.Met470Arg variant compound heterozygous with p.Arg758Cys. Lower limb muscle MRI revealed progressive fatty degeneration of specific posterior compartment muscles. Patients' spiroergometric profiles showed that anoctaminopathy significantly impaired oxidative capacity with increasing ventilation. CONCLUSIONS: Our findings support earlier reports that anoctaminopathy progresses slowly and demonstrate that the disease impairs the capacity for aerobic exercise.

O estado da arte das síndromes autoinflamatórias associadas à criopirina / The state of the art of cryopyrin-associated periodic syndromes

As síndromes autoinflamatórias associadas à criopirina (CAPS) compreendem um grupo espectral de doenças raras autoinflamatórias. Todas estas doenças estão relacionadas ao inflamassoma NLRP3, sendo que de 50-60% dos pacientes apresentam mutações ao longo do gene NLRP3. Clinicamente, febre recorrente associada à urticária neutrofílica e outros sintomas sistêmicos são o grande marco clínico, comum a todo o espectro. O bloqueio da interleucina-1 trouxe grande alívio ao tratamento destas desordens, mas variações na resposta clínica podem ser observadas, principalmente nos espectros mais graves. Neste trabalho os autores trazem uma revisão do estado da arte das doenças autoinflamatórias CAPS. Foi realizado levantamento de literatura e, ao final, 49 artigos restaram como base para construção do texto final. O trabalho traz de forma narrativa os principais pontos relacionados a imunofisiopatologia, manifestação clínica, diagnóstico, tratamento, complicações e novas armas diagnósticas, e terapia gênica.

Cryopyrin-associated periodic syndromes (CAPS) comprise a spectrum of rare autoinflammatory disorders. They are all related to the NLRP3 inflammasome, and 50-60% of the patients harbor mutations along the NLRP3 gene. Clinically, recurrent fever associated with neutrophilic urticaria and other systemic symptoms are a hallmark of all the disorders in the spectrum. Biologic drugs that can block interleukin-1 were a milestone for the treatment of such rare diseases, although variability in clinical response to this therapeutic intervention were observed, especially in those affected by severe phenotypes. In this paper, the authors provide a state-of-the-art review of CAPS. A literature search was performed and, finally, 49 articles remained for the construction of the final manuscript. The article presents a narrative review focused on the topics related to immune pathophysiology, clinical manifestations, diagnosis, treatment, complications and new therapeutic options, and gene therapy.
