ARHGAP12

Chr 10

Rho GTPase activating protein 12

This gene encodes a GTPase-activating protein that converts Rho-type GTPases to their inactive GDP-bound state, regulating cellular processes including invasion and adhesion. Mutations cause autosomal recessive intellectual disability with variable features that may include developmental delay and neurological abnormalities. The gene is highly constrained against loss-of-function variation in the general population.

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.
