SORBS3

Chr 8

sorbin and SH3 domain containing 3

Also known as: SCAM-1, SCAM1, SH3D4

The protein encoded by this gene is an SH3 domain-containing adaptor protein called vinexin that regulates actin stress fiber formation, cell spreading, and JNK/SAPK signaling activation. This gene is extremely intolerant to loss-of-function mutations (pLI ~1.0), but specific disease associations have not been established based on the provided information. The inheritance pattern and clinical phenotypes associated with SORBS3 mutations are not defined in the available data.

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.
