CAVIN4

Chr 9

caveolae associated protein 4

Also known as: MURC, cavin-4

The protein modulates caveolae morphology in cardiomyocytes and regulates cardiac hypertrophic responses through MAPK signaling and Rho/ROCK pathway activation. Mutations cause autosomal recessive rippling muscle disease, a neuromuscular disorder characterized by muscle hyperexcitability and rippling contractions triggered by mechanical stimuli. The gene shows tolerance to loss-of-function variants in the general population.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function 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.
