A de novo frameshift variant in MED13 gene in a patient with autism spectrum disorder and magnetic resonance imaging abnormalities mimicking tuberous sclerosis.

The mediator complex subunit 13 (MED13) gene is implicated in neurodevelopmental disorders including autism spectrum disorder (ASD), intellectual disability, and speech delay with varying severity and course. Additional, extra central nervous system, features include eye or vision problems, hypotonia, congenital heart abnormalities, and dysmorphisms. We describe a 7-year- and 4-month-old girl evaluated for ASD whose brain magnetic resonance imaging was suggestive of multiple cortical tubers. The exome sequencing (ES - trio analysis) uncovered a unique, de novo, frameshift variant in the MED13 gene (c.4880del, D1627Vfs*17), with a truncating effect on the protein. This case report thus expands the phenotypic spectrum of MED13-related disorders to include brain abnormalities.

The association between computed tomography attenuation value of renal angiomyolipoma associated with tuberous sclerosis complex and response to everolimus.

BACKGROUND: The response to everolimus in patients with renal angiomyolipoma associated with tuberous sclerosis complex (TSC-RAML) varies among individuals. This study aims to identify potential factors associated with the response to everolimus. METHOD: We retrospectively examined data encompassing age, gender, tumor size, computed tomography attenuation value (CT value), CT enhancement, and tumor reduction rate in patients with TSC-RAML undergoing everolimus in two previously registered clinical trials. RESULT: A total of 33 participants (29.33 ± 6.63 years old, 20 females) were included. The correlation analysis conducted separately for tumors located in the left and right kidneys revealed significant negative correlations (P < 0.05) between tumor reduction rate and age, as well as tumor size. While significant positive correlations (P < 0.05) were observed between tumor reduction rate and unenhanced CT value as well as CT enhancement. Nonetheless, based on multiple linear regression analysis, unenhanced CT value emerged as the sole-independent predictor of tumor reduction rate among age, gender, tumor size, unenhanced CT value and CT enhancement for both left (coefficient = 0.00319, P < 0.0001) and right kidneys (coefficient = 0.00315, P = 0.0104). Notable reductions were observed in unenhanced CT value (- 3.81 vs - 24.70HU, P < 0.0001) and CT enhancement (48.16 vs 33.56HU, P < 0.0001) following a 3-month administration of everolimus. The decline in both unenhanced CT value and tumor size predominantly occurred within the initial 3 months, subsequently maintaining a relatively stable level throughout the treatment. CONCLUSION: The unenhanced CT value of TSC-RAML showed an independent correlation with the response to everolimus, suggesting its potential as a predictor of everolimus efficacy in patients with TSC-RAML.

Exploring the intersection of tuberous sclerosis and precocious puberty unveiled by hematocolpos.

We present the case of a 6-year-old girl who initially presented with acute pelvic pain, ultimately diagnosed with imperforate hymen leading to hematocolpos. Further investigation revealed additional clinical features including academic struggles, mood swings, and cutaneous findings, prompting consideration of a neurocutaneous syndrome. Magnetic Resonance Imaging (MRI) revealed features consistent with tuberous sclerosis complex (TSC), including radial migration lines in the subcortical white matter and an incidental arachnoid cyst. Notably, this case exhibited a unique presentation with absence of typical TSC findings such as subependymal nodules or cortical tubers. Additionally, precocious puberty, rarely associated with TSC, was observed, suggesting a potential link between hypothalamic lesions and hormonal imbalance. This case underscores the importance of comprehensive evaluation in pediatric patients presenting with seemingly unrelated symptoms, as it may unveil underlying conditions necessitating tailored management strategies.

Sporadic subependymal giant cell astrocytoma with somatic TSC2 mutation: A case report.

Subependymal giant cell astrocytoma (SEGA) is a rare circumscribed astrocytic glioma that occurs in approximately 25% of all tuberous sclerosis (TSC) cases. Herein, we discuss an atypical presentation of SEGA, including the genetic alterations, impact on clinical presentation, and the determinants of each medical and surgical treatment option. A 14-year-old girl presented with intermittent headache and a right intraventricular mass originating near the foramen of Monro. The tumor's proximity to critical structures necessitated maximum safe resection, which improved her symptoms. Histological findings indicated SEGA, and genetic sequencing revealed a TSC2 mutation. However, complete clinical and radiological evaluations failed to reveal TSC. Two months later, a new subependymal nodule was incidentally found. She had a recurrent left occipital horn lesion and diffuse smooth leptomeningeal enhancement with no spine drop metastases. She was administered everolimus as the tumor was considered unresectable. Subsequent imaging revealed a reduction in both residual and new lesions.

Predictive model for epileptogenic tubers from all tubers in patients with tuberous sclerosis complex based on 18F-FDG PET: an 8-year single-centre study.

BACKGROUND: More than half of patients with tuberous sclerosis complex (TSC) suffer from drug-resistant epilepsy (DRE), and resection surgery is the most effective way to control intractable epilepsy. Precise preoperative localization of epileptogenic tubers among all cortical tubers determines the surgical outcomes and patient prognosis. Models for preoperatively predicting epileptogenic tubers using 18F-FDG PET images are still lacking, however. We developed noninvasive predictive models for clinicians to predict the epileptogenic tubers and the outcome (seizure freedom or no seizure freedom) of cortical tubers based on 18F-FDG PET images. METHODS: Forty-three consecutive TSC patients with DRE were enrolled, and 235 cortical tubers were selected as the training set. Quantitative indices of cortical tubers on 18F-FDG PET were extracted, and logistic regression analysis was performed to select those with the most important predictive capacity. Machine learning models, including logistic regression (LR), linear discriminant analysis (LDA), and artificial neural network (ANN) models, were established based on the selected predictive indices to identify epileptogenic tubers from multiple cortical tubers. A discriminating nomogram was constructed and found to be clinically practical according to decision curve analysis (DCA) and clinical impact curve (CIC). Furthermore, testing sets were created based on new PET images of 32 tubers from 7 patients, and follow-up outcome data from the cortical tubers were collected 1, 3, and 5 years after the operation to verify the reliability of the predictive model. The predictive performance was determined by using receiver operating characteristic (ROC) analysis. RESULTS: PET quantitative indices including SUVmean, SUVmax, volume, total lesion glycolysis (TLG), third quartile, upper adjacent and standard added metabolism activity (SAM) were associated with the epileptogenic tubers. The SUVmean, SUVmax, volume and TLG values were different between epileptogenic and non-epileptogenic tubers and were associated with the clinical characteristics of epileptogenic tubers. The LR model achieved the better performance in predicting epileptogenic tubers (AUC = 0.7706; 95% CI 0.70-0.83) than the LDA (AUC = 0.7506; 95% CI 0.68-0.82) and ANN models (AUC = 0.7425; 95% CI 0.67-0.82) and also demonstrated good calibration (Hosmer‒Lemeshow goodness-of-fit p value = 0.7). In addition, DCA and CIC confirmed the clinical utility of the nomogram constructed to predict epileptogenic tubers based on quantitative indices. Intriguingly, the LR model exhibited good performance in predicting epileptogenic tubers in the testing set (AUC = 0.8502; 95% CI 0.71-0.99) and the long-term outcomes of cortical tubers (1-year outcomes: AUC = 0.7805, 95% CI 0.71-0.85; 3-year outcomes: AUC = 0.8066, 95% CI 0.74-0.87; 5-year outcomes: AUC = 0.8172, 95% CI 0.75-0.87). CONCLUSIONS: The 18F-FDG PET image-based LR model can be used to noninvasively identify epileptogenic tubers and predict the long-term outcomes of cortical tubers in TSC patients.

Amelioration of the brain structural connectivity is accompanied with changes of gut microbiota in a tuberous sclerosis complex mouse model.

Tuberous sclerosis complex (TSC) is a genetic disease that causes benign tumors and dysfunctions in many organs, including the brain. Aside from the brain malformations, many individuals with TSC exhibit neuropsychiatric symptoms. Among these symptoms, autism spectrum disorder (ASD) is one of the most common co-morbidities, affecting up to 60% of the population. Past neuroimaging studies strongly suggested that the impairments in brain connectivity contribute to ASD, whether or not TSC-related. Specifically, the tract-based diffusion tensor imaging (DTI) analysis provides information on the fiber integrity and has been used to study the neuropathological changes in the white matter of TSC patients with ASD symptoms. In our previous study, curcumin, a diet-derived mTOR inhibitor has been shown to effectively mitigate learning and memory deficits and anxiety-like behavior in Tsc2+/- mice via inhibiting astroglial proliferation. Recently, gut microbiota, which is greatly influenced by the diet, has been considered to play an important role in regulating several components of the central nervous system, including glial functions. In this study, we showed that the abnormal social behavior in the Tsc2+/- mice can be ameliorated by the dietary curcumin treatment. Second, using tract-based DTI analysis, we found that the Tsc2+/- mice exhibited altered fractional anisotropy, axial and radial diffusivities of axonal bundles connecting the prefrontal cortex, nucleus accumbens, hypothalamus, and amygdala, indicating a decreased brain network. Third, the dietary curcumin treatment improved the DTI metrics, in accordance with changes in the gut microbiota composition. At the bacterial phylum level, we showed that the abundances of Actinobacteria, Verrucomicrobia, and Tenericutes were significantly correlated with the DTI metrics FA, AD, and RD, respectively. Finally, we revealed that the expression of myelin-associated proteins, myelin bassic protein (MBP) and proteolipid protein (PLP) was increased after the treatment. Overall, we showed a strong correlation between structural connectivity alterations and social behavioral deficits, as well as the diet-dependent changes in gut microbiota composition.

Abnormality of Early White Matter Development in Tuberous Sclerosis Complex and Autism Spectrum Disorder: Longitudinal Analysis of Diffusion Tensor Imaging Measures.

Background: Abnormalities in white matter development may influence development of autism spectrum disorder in tuberous sclerosis complex (TSC). Our goals for this study were as follows: (1) use data from a longitudinal neuroimaging study of tuberous sclerosis complex (TACERN) to develop optimized linear mixed effects models for analyzing longitudinal, repeated diffusion tensor imaging metrics (fractional anisotropy, mean diffusivity) pertaining to select white matter tracts, in relation to positive Autism Diagnostic Observation Schedule-Second Edition classification at 36 months, and (2) perform an exploratory analysis using optimized models applied to all white matter tracts from these data. Methods: Eligible participants (3-12 months) underwent brain magnetic resonance imaging (MRI) at repeated time points from ages 3 to 36 months. Positive Autism Diagnostic Observation Schedule-Second Edition classification at 36 months was used. Linear mixed effects models were fine-tuned separately for fractional anisotropy values (using fractional anisotropy corpus callosum as test outcome) and mean diffusivity values (using mean diffusivity right posterior limb internal capsule as test outcome). Fixed effects included participant age, within-participant longitudinal age, and autism spectrum disorder diagnosis. Results: Analysis included data from n = 78. After selecting separate optimal models for fractional anisotropy and mean diffusivity values, we applied these models to fractional anisotropy and mean diffusivity of all 27 white matter tracts. Fractional anisotropy corpus callosum was related to positive Autism Diagnostic Observation Schedule-Second Edition classification (coefficient = 0.0093, P = .0612), and mean diffusivity right inferior cerebellar peduncle was related to positive Autism Diagnostic Observation Schedule-Second Edition classification (coefficient = -0.00002071, P = .0445), though these findings were not statistically significant after multiple comparisons correction. Conclusion: These optimized linear mixed effects models possibly implicate corpus callosum and cerebellar pathology in development of autism spectrum disorder in tuberous sclerosis complex, but future studies are needed to replicate these findings and explore contributors of heterogeneity in these models.

Hemorragia intracraniana en un feto con trisomia 21 y rabdomiomas cardiacos: diagnostico diferencial de esclerosis tuberosa: estudio antenatal a propósito de un caso / Intracranian hemorrhage in a fetus with trisomy 21 and cardiac rhabdomyomas: differential diagnosis of tuberous sclerosis: antenatal study regarding a case

INTRODUCCIÓN: El Síndrome de Down (SD) es una de las aneuploidías más frecuentes. En Chile, la incidencia es de 2.2 por 1000 nv. La esclerosis tuberosa (ET) es una enfermedad genética autosómica dominante con una prevalencia de 1:600 a 1:10.000 nacidos vivos (nv) que se sospecha prenatalmente por la presencia de rabdomiomas cardiacos. Los tumores cardiacos fetales tienen una prevalencia de 1:10000 nv, los más prevalentes son los Rabdomiomas. El hallazgo de tumores intracraneanos son infrecuentes, dentro del diagnóstico diferencial es necesario descartar la Hemorragia Intraventricular (HIV). CASO CLÍNICO: Paciente de 29 años, M2, Derivada a nuestro centro a las 27+4 semanas para evaluación ecográfica. Entre los hallazgos se encuentran tumores intracardiacos en ventrículo derecho y marcadores blandos para alto riesgo de aneuploidía, por lo que se realiza cariotipo (amniocentesis genética: 47, XX+21). A las 32+0 semanas en una nueva evaluación presenta imagen hiperecogénica sugerente de tumor intracerebral. Se solicita resonancia magnética fetal que informa hemorragia intraventricular (HIV). El parto ocurre con un recién nacido de término, fenotipo concordante con Trisomía 21, ecocardiograma confirma dos tumores intracardiacos (Rabdomiomas) y ecografía cerebral confirma el diagnóstico de HIV Grado III derecho. Ante el diagnóstico diferencial de ET, se realiza ANGIO-TAC que resulta negativo para ET. DISCUSIÓN: En la evaluación ecográfica antenatal, la presencia de tumores intracardiacos asociados a tumor cerebral hace plantear el diagnóstico de una ET. El diagnóstico antenatal de tumores cerebrales vs HIV por ultrasonido es difícil. La resonancia es un examen complementario de gran ayuda, permitiendo un diagnóstico de certeza. La HIV fetal es un diagnóstico poco frecuente de diagnostico prenatal asociado a feto con trisomia 21.

INTRODUCTION: Down Syndrome (DS) is one of the most frequent aneuploidies. In our country its incidence is 2.2 every 1000 newborns. Tuberous sclerosis (TS) is a dominant autosomal genetic disease with a prevalence of 1:6000 to 1:10.000 newborns, this disease is suspected by the finding of cardiac rhabdomyomas. Rhabdomyomas are the most prevalent fetal heart tumors. Intracranial tumors are a rare prenatal finding in ultrasound the main differential diagnosis is Intraventricular Hemorrhage (IVH). The Objective of this paper is present a case report of a fetus with trisomy 21 plus rhabdomyomas and cranial tumors. CASE REPORT: 29 years old patient, referred for ultrasound at 27+4 week. Cardiac tumors and aneuploidy soft markers are found. Genetic amniocentesis is performed (Result: 47, XX+21). At 32+0 weeks ultrasound finding of intracranial tumor. Fetal MRI was performed which reports suspected IVH. Confirmed postnatally. Baby was delivered at term. Neonatal findings: Trisomy 21 phenotype, Echocardiogram with two cardiac tumors (Rhabdomyomas), neonatal brain ultrasound confirms Grade III - IVH. To rule out TS, an Angio-CT is performed which is negative for the disease. DISCUSSION: Cardiac Tumors associated to brain tumors in antenatal period make TS a possible diagnosis. Differentiate brain tumors and IVH by ultrasound is very difficult. MRI is a very helpful tool for an accurate diagnostic. IVH is a rare antenatal diagnosis. Not reported before in a baby with trisomy 21.

Diagnóstico prenatal de rabdomioma fetal asociado a esclerosis tuberosa: a propósito de un caso / Prenatal diagnosis of fetal rhabdomyoma associated with tuberous sclerosis

Los rabdomiomas son los tumores benignos cardíacos más frecuentes encontrados en vida fetal y postnatal, asociándose frecuentemente a esclerosis tuberosa. A propósito de un caso manejado en nuestra maternidad el año 2014 se revisó la literatura existente sobre su diagnóstico, manejo, implicancias pronósticas. Se trata de una embarazada de 23 años que fue referida a las 25 semanas a nuestro servicio, el estudio ecográfico revela tres imágenes cardiacas concordantes con rabdomiomas en las paredes ventriculares y el septum. No se detectan otras anormalidades y se controla en forma seriada con ultrasonido. Se realiza a las 33 semanas resonancia nuclear magnética fetal con el objetivo de evidenciar signos de esclerosis tuberosa los cuales se evidencian en el examen y se confirman en exámenes postnatales. Se comenta el diagnóstico diferencial con otros neoplasias benignas cardiacas como teratomas, fibromas y hemangiomas. Las posibles complicaciones de los rabdomiomas dependerán de su ubicación y tamaño, produciendo alteraciones en flujo o bien menos frecuentemente arritmias. La asociación más importante de esta patología es con esclerosis tuberosa de manera que se debe realizar una cuidadosa anamnesis familiar, estudios de imágenes que deben abarcar el SNC, corazón y riñones. Finalmente en ese contexto realizar la mejor consejería a los padres.

Rhabdomyomas are the most common benign cardiac tumors found in fetal and postnatal life, frequently being associated with tuberous sclerosis. In relation to a case handled in our maternity unit in 2014, existing literature on cardiac rhabdomyomas diagnosis, management and prognostic implications, was revised. The case concerned a 25 week pregnant 23 year old patient, who was referred to our facility; ultrasound examination reveals three cardiac images consistent with rhabdomyomas in the ventricular walls and the septum. No other abnormalities are detected and the patient is monitored with a series of ultrasound. At 33 weeks a fetal magnetic resonance imaging is performed in order to show signs of tuberous sclerosis which are noted in the examination and confirmed in post natal tests. Differential diagnosis with other benign cardiac neoplasms such as teratomas, fibromas and hemangiomas is discussed. Possible complications of the rhabdomyomas will depend on its location and size, producing changes in flow or less frequent arrhythmias. The most important association of this pathology is with tuberous sclerosis, therefore the family medical history must be carefully evaluated, and imaging controls that should include the CNS, heart and kidneys. Finally in this context give the best counseling to the parents.

Onychogryphosis in tuberous sclerosis complex: an unusual feature

Abstract Onychogryphosis is an acquired nail plate change. It often affects the toenail and is characterized by an opaque, yellow-brownish nail plate that is distorted, grossly thickened, elongated, and partly curved resembling a ram's horn. Tuberous sclerosis complex is a multisystem disorder associated with high rates of mental retardation, autism, cognitive impairment, behavioral problems, or seizures. Nail disease can also be associated, which is a concern to patients due to pain and nail distortion. We reported a typical tuberous sclerosis complex patient with distinctive clinical features of a ram's horn nails, which presented a great challenge to surgical treatment and nail restoration.

TSC2/PKD1 contiguous gene syndrome, with emphasis on a case with an atypical mild polycystic kidney phenotype and a novel genetic variant / Síndrome de genes contiguos TSC2/PKD1 con énfasis en un caso con un fenotipo atípico de riñón poliquístico leve y una nueva variante genética

About 80% of patients with tuberous sclerosis complex (TSC) present renal involvement, usually as angiomyolipomas followed by cystic disease. An early diagnosis of polycystic kidney disease (PKD) in such patients is frequently related to the TSC2/PKD1 contiguous gene syndrome (PKDTS). Molecular confirmation of PKDTS is important for a prompt diagnosis, which can be complicated by the phenotypic heterogeneity of PKD and the absence of a clear phenotype-genotype correlation. Herein, we report three PKDTS pediatric patients. The case 3 did not present a classic PKDTS phenotype, having only one observable cyst on renal ultrasound at age 4 and multiple small cysts on magnetic resonance imaging at age 15. In this patient, chromosomal microarray analysis showed a gross deletion of 230.8 kb that involved TSC2, PKD1 and 13 other protein-coding genes, plus a heterozygous duplication of a previously undescribed copy number variant of 242.9kb that involved six protein-coding genes, including SSTR5, in the 16p13.3 region. Given the observations that the case 3 presented the mildest renal phenotype, harbored three copies of SSTR5, and the reported inhibition of cystogenesis (specially in liver) observed with somatostatin analogs in some patients with autosomal dominant PKD, it can be hypothesized that other genetic factors as the gene dosage of SSTR5 may influence the PKD phenotype and the progression of the disease; however, future work is needed to examine this possibility

Un 80% de los pacientes con complejo de esclerosis tuberosa (CET) presentan afectación renal, generalmente angiomiolipomas, seguidos de enfermedad quística. Un diagnóstico temprano de la enfermedad renal poliquística (ERP) en estos pacientes se relaciona con frecuencia con el síndrome de genes contiguos TSC2/PKD1 (PKDTS). La confirmación molecular de PKDTS es importante para establecer un diagnóstico oportuno, que puede complicarse por la heterogeneidad fenotípica de PKD y la ausencia de una clara correlación entre fenotipo y genotipo. En este artículo presentamos los casos de 3 pacientes pediátricos con PKDTS. El caso 3 no presentó un fenotipo PKDTS clásico, con solo un quiste observable en la ecografía renal a los 4 años y numerosos quistes pequeños en la resonancia magnética a los 15 años. En este paciente, el análisis de microarreglos para análisis cromosómico global mostró una eliminación total de 230,8 kb que involucró a TSC2, PKD1 y otros 13 genes codificantes de proteínas, más una duplicación heterocigota para una variante de número de copias no descrita previamente de 242,9 kb que involucró a 6 genes codificantes de proteínas, entre ellos SSTR5, en la región 16p13.3. Dado que el caso 3 mostraba el fenotipo renal menos severo, contaba con tres copias del gen SSTR5 y a que se ha observado una inhibición en la cistogénesis (especialmente en el hígado) con los análogos de somatostatina en algunos pacientes con ERP autosómica dominante, podemos hipotetizar que existen otros factores genéticos como la dosis génica de SSTR5 que pudieran influir en el fenotipo y la progresión de la ERP; sin embargo, se necesitan estudios adicionales para investigar esta posibilidad
