ZC2HC1B

Chr 6

zinc finger C2HC-type containing 1B

The protein is predicted to bind zinc ions. Mutations in this gene cause autosomal recessive intellectual disability with microcephaly and seizures, typically with onset in infancy or early childhood. This gene is not highly constrained against loss-of-function variants.

This gene has evidence for multiple mechanisms of pathogenicity (dominant-negative and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to dominant-negative as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

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.
