WASHC1

Overview

WASHC1 (WASH Complex Subunit 1, previously reported as WASH1) encodes a core component of the WASH actin-nucleation complex involved in endosomal sorting and recycling. It was identified as a significantly mutated gene preferentially targeted in African American (AA) colorectal cancers relative to Caucasian CRCs, suggesting a potential ethnicity-associated driver role.

Alterations observed in the corpus

  • Identified as one of 20 significantly mutated genes preferentially targeted in African American CRCs (n=103 AA discovery + validation vs n=129 Caucasian); part of a 15-gene set with higher mutation frequency in AA than Caucasian CRCs PMID:25583493

Cancer types (linked)

  • COADREAD — significantly mutated in African American CRCs; part of a 15-gene set accounting for 41% of AA CRCs vs 15% of Caucasian CRCs PMID:25583493

Co-occurrence and mutual exclusivity

Therapeutic relevance

  • No direct drug targeting reported in this corpus; inclusion in an AA-specific CRC driver gene panel may have implications for ethnicity-stratified treatment or screening strategies PMID:25583493

Open questions

  • Functional consequences of WASHC1 mutations in CRC have not been experimentally validated; the paper’s conservative selection criterion (significant in both discovery and validation cohorts) provides statistical support but does not establish mechanism PMID:25583493
