Genes affected

WASHC1 (HGNC:24361): (WASH complex subunit 1) Enables alpha-tubulin binding activity and ubiquitin protein ligase binding activity. Involved in several processes, including Arp2/3 complex-mediated actin nucleation; endosomal transport; and positive regulation of pseudopodium assembly. Located in early endosome. Part of WASH complex. Colocalizes with exocyst. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
