ZNF662

Chr 3

zinc finger protein 662

NCBI Gene: 389114ENSG00000182983UniProt: Q6ZS27

The protein functions as a DNA-binding transcription factor that regulates gene expression by RNA polymerase II in the nucleus. Mutations in this gene cause autosomal dominant developmental and epileptic encephalopathy with onset in infancy, characterized by severe intellectual disability, epilepsy, and developmental delays. This gene shows low constraint against loss-of-function variants, suggesting tolerance to such changes in the general population.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
