WASHC1

Chr 9

WASH complex subunit 1

Also known as: FAM39E, WASH, WASH1

The WASHC1 protein is a component of the WASH complex that activates actin polymerization at endosome surfaces, regulating endosomal trafficking and receptor recycling. Mutations cause Ritscher-Schinzel syndrome, a rare autosomal recessive disorder characterized by intellectual disability, cerebellar hypoplasia, and craniofacial anomalies. This gene shows high constraint against loss-of-function variants, indicating that biallelic mutations are required for disease manifestation.

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.
