• NM_001378090.1:c.1384G>C

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001378090.1(WASHC1):​c.1384G>C​(p.Asp462His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D462N) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 31)
• Consequence: WASHC1 NM_001378090.1 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.47

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

Verdict is Uncertain_significance. Variant got 2 ACMG points.

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