SCN8A disorders present a wide spectrum of symptoms, from normal development to severe epilepsy. This study identifies new SCN8A variants and characterizes a novel loss-of-function variant, expanding understanding of these conditions.
Area of Science:
- Genetics and Neurology
- Molecular Biology
Background:
- SCN8A-related disorders encompass a spectrum of conditions including developmental and epileptic encephalopathy 13, benign familial infantile seizures 5, and cognitive impairment with cerebellar ataxia.
- These disorders are caused by pathogenic variations in the SCN8A gene.
Conclusions:
- This study broadens the known clinical and genotypic spectrum of SCN8A-related disorders.
- A novel loss-of-function SCN8A variant was characterized, contributing to the understanding of its functional impact.
