WASF3

Chr 13

WASP family member 3

Also known as: Brush-1, SCAR3, WAVE3

The WASF3 protein is a downstream effector that transmits signals from tyrosine kinase receptors and small GTPases to the actin cytoskeleton, regulating cell morphology and cytoskeletal organization. Mutations cause autosomal dominant intellectual disability with macrocephaly, seizures, and speech delay. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.467), consistent with its role in essential cellular processes.
