ZNF397

Chr 18

zinc finger protein 397

Also known as: ZNF47, ZSCAN15

This gene encodes a transcriptional repressor containing a SCAN domain and zinc finger repeats that localizes to centromeres during cell division. Mutations in ZNF397 cause autosomal dominant neurodevelopmental disorder with epilepsy and hypotonia. The gene is not highly constrained against loss-of-function variants, suggesting the pathogenic variants may act through other mechanisms.

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.
