Classic Ataxia–Telangiectasia associated with a homozygous missense ATM variant: A case report

Ataxia–telangiectasia (A-T) is a rare autosomal recessive disorder caused by mutations in the ATM gene, characterized by progressive cerebellar ataxia, telangiectasias, immunodeficiency, and increased cancer risk Reporting the phenotypic spectrum of ATM variants is essential to refine genotype–phenotype correlations. W...

A homozygous missense variant in NRROS gene is associated with intracranial calcifications, neurodegeneration, and severe infantile epilepsy syndrome.

Biallelic loss-of-function variants in NRROS (Negative regulator of reactive oxygen species, previously LRRC33) cause a progressive neurodegenerative disorder characterized by early-onset seizures with brain calcifications. To date, 16 affected individuals from 13 unrelated families have been reported for this conditio...

A Heterozygous Variant in the GABBR2 Gene in a Girl With Clinical Classic Rett Syndrome

ABSTRACT Background Rett syndrome (RTT) is a neurodevelopmental disorder mainly affecting females and may start with seemingly normal early development but leads to developmental stagnation, regression, and characteristic neurological symptoms. While most cases involve MECP2 variants, other genes have been implicated i...

Clinical and Genetic Findings in a Turkish Family With the Recurrent Homozygous EEFSEC p.Asp390Ala Variant.

The EEFSEC gene encodes eukaryotic elongation factor selenocysteine-tRNA-specific, an essential component of the selenoprotein biosynthesis machinery required for normal neurodevelopment. Biallelic EEFSEC variants have recently been associated with a rare autosomal recessive neurodevelopmental disorder with variable ne...
