• WASHC2C p.Thr246Ile

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.

The NM_001330074.2(WASHC2C):​c.737_738delCCinsTT​(p.Thr246Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Uncertain significance in ClinVar.

Genes affected

WASHC2C (HGNC:23414): (WASH complex subunit 2C) Enables phosphatidylinositol phosphate binding activity; phosphatidylinositol-3,4-bisphosphate binding activity; and retromer complex binding activity. Involved in several processes, including endosomal transport; negative regulation of barbed-end actin filament capping; and regulation of substrate adhesion-dependent cell spreading. Located in cytosol; early endosome; and nucleolus. Part of WASH complex. [provided by Alliance of Genome Resources, Apr 2022]
