CNTNAP3C

Chr 9

contactin associated protein family member 3C

The protein is predicted to function in cell adhesion and is located in cellular membranes. However, there is currently insufficient clinical data available to establish definitive disease associations, inheritance patterns, or phenotypic consequences of CNTNAP3C mutations. This gene requires further research to determine its role in human disease.

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.
