RIMS3

Chr 1

regulating synaptic membrane exocytosis 3

Also known as: NIM3, RIM 3, RIM3

The RIMS3 protein regulates synaptic membrane exocytosis and serves as a structural constituent of the presynaptic active zone, where it controls synaptic vesicle release. Mutations in RIMS3 cause autosomal recessive cone-rod dystrophy, a retinal disorder affecting photoreceptor function. The gene shows tolerance to loss-of-function variants (pLI = 0.0001), consistent with a recessive inheritance pattern.

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.

GOFprediction above median

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.
