Atypical Clinical Course of Griscelli Syndrome Type 2 With Primarily Neurologic Presentation and Adult‐Onset in a 46‐Year‐Old Male

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Griscelli Syndrome Type 2 (GS2) is a rare autosomal recessive disorder caused by pathogenic mutations in the RAB27A gene. Typically, it is characterized by cutaneous hypopigmentation, immunodeficiency, with or without neurological abnormalities secondary to hemophagocytic lymphohistiocytosis (HLH). Without treatment, GS2 often results in fatal

Glial cell activation precedes neurodegeneration in the cerebellar cortex of the YG8–800 murine model of Friedreich ataxia

Friedreich ataxia is a hereditary neurodegenerative disorder resulting from reduced levels of the protein frataxin due to an expanded GAA repeat in the FXN gene.

Motor Dysfunctions and Neuropathology in Mouse Models of Spinocerebellar Ataxia Type 2: A Comprehensive Review

, 2016
Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant ataxia caused by an expansion of CAG repeats in the exon 1 of the gene ATXN2, conferring a gain of toxic function that triggers the appearance of the disease phenotype.

A Refined Vestibular Romberg Test to Differentiate Somatosensory from Vestibular-Induced Disequilibrium

Diagnostics
Background: The vestibular Romberg test, which assesses the deterioration of balance while standing on rubber foam with closed eyes, is a well-established method in the physical neurological assessment of patients with peripheral vestibulopathy.

Long‐Term Follow Up of Two Patients With Variants in the Cluster 1031‐1159 of TRRAP Gene: Expanding the Phenotype of Developmental Delay With or Without Dysmorphic Facies and Autism

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The transformation/transcription domain‐associated protein (TRRAP) gene encodes a large multidomain protein, a member of the phosphatidylinositol 3‐kinase‐related kinase (PIKK) family. TRRAP is a component of the histone acetyltransferase (HAT) complex, and it plays an important role in gene transcription, DNA repair, and cell‐cycle regulation.

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.

Impact of ataxia aetiology on self-reported mental health, fatigue, cognition and ataxia symptom severity

Discover Psychology
Introduction It has been increasingly recognised that the impact of Ataxia extends beyond physical and motor symptomology. However, it is less known whether self-reported non-motor and ataxia symptom severity varies across ataxias of differing aetiology,

Defining Features of Gabriele‐de Vries Syndrome in Adults: A Case Report and Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gabriele‐de Vries syndrome (GADEVS) is a neurodevelopmental disorder caused by heterozygous pathogenic variants in the YY1 gene. Like most rare genetic syndromes, the adult manifestations of GADEVS remain poorly defined. Here, we describe the oldest patient reported to date with GADEVS—a 63‐year‐old woman with a c.1177_1179del YY1 variant ...

Unraveling a Diagnostic Enigma: A TECPR2 Case Solved Through Multi‐Omic Genomics

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT TECPR2 is a key regulator of autophagy, encoded by the TECPR2 gene. Pathogenic variants in this gene have been linked to a rare hereditary sensory and autonomic neuropathy with intellectual disability (HSAN9). We report a teenage female with a syndromic intellectual disability disorder associated with neuromuscular abnormalities.
