Article Abstract

Charcot-Marie-Tooth 4C is characterized by early-onset, rapid progression, and mainly associated with gene mutations. We reported a male patient carrying a novel heterozygous nonsense mutation in gene along with a heterozygous known pathogenic mutation. Symptoms began at 15 months and by 14 years, he presented significant motor impairment. Both parents exhibited one of the mutations in the heterozygous state, while his 8-year-old brother carried the same compound heterozygosity, showing only a mild phenotype. In our case, we discussed the contribution of compound heterozygosity to intrafamilial variability in Charcot-Marie-Tooth and the role of modifying genes.

encodes NADH: ubiquinone oxidoreductase core subunit V1, a key component of mitochondrial Complex 1. Biallelic pathogenic variants in this gene produce a broad and variable phenotypic spectrum in affected individuals, including ophthalmoplegia, developmental delays, brain imaging abnormalities, and recurrent episodes of emesis and lactic acidemia. We report female siblings compound heterozygous for two missense variants (Arg40Gln, Val245Met) in with unusual presentations of this condition.

Introduction: Retinal dysfunction associated with CACNA2D4 gene defects is a rare disorder of photoreceptor to bipolar cell signaling. We report two affected siblings presenting a surprising disparity of retinal involvement.

Materials And Methods: Patients underwent complete ocular examination, multimodal fundus imaging, and full-field electroretinography (ffERG).

The HECW2 gene, essential for neurodevelopment, plays a critical role in maintaining cellular homeostasis and regulating key pathways in the nervous system. Deleterious variants in the HECW2 gene have been associated with developmental delay, intellectual disability, hypotonia and epilepsy, as well as dysmorphic features. We present the case of an infant with a novel variant in HECW2 with an unusual clinical presentation and a progressive disease course, showing three successive electroclinical patterns, consisting of burst suppression characteristic of early infantile developmental and epileptic encephalopathy, subcontinuous myoclonic seizures and infantile epileptic spasms syndrome without hypsarrhythmia, occurring over a short period of time.

Background: The phenotypic outcomes of de novo variants (DNVs) in autism spectrum disorder (ASD) exhibit wide variability. To date, no study has comprehensively estimated DNV effects accounting for familial phenotypic background.

Methods: To evaluate DNV effects in a family-relative context, we defined within-family standardized deviations (WFSD) by subtracting phenotype scores of unaffected family members and standardizing the result.

Purpose: The gamma-aminobutyric acid type A receptor subunit gamma-2 (GABRG2) gene is a well-known causative gene for genetic epilepsy with febrile seizures plus (GEFS+), exhibiting a broad phenotypic spectrum. This study aimed to describe the clinical variability among family members with a novel GABRG2 variant.

Methods: We analyzed the clinical and genetic findings of three sisters and their father.
