Genes affected

WASHC4 (HGNC:29174): (WASH complex subunit 4) This gene encodes a component of the WASH complex, which functions in the intracellular transport of endosomes. Mutations in this gene have been detected in individuals with autosomal recessive cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 9: AlphaMissense, BayesDel_noAF, Cadd, Eigen, phyloP100way_vertebrate, PrimateAI, PROVEAN, REVEL, REVEL [when BayesDel_addAF, max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.17849016).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00148 (226/152334) while in subpopulation NFE AF = 0.00273 (186/68028). AF 95% confidence interval is 0.00241. There are 1 homozygotes in GnomAd4. There are 92 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High Homozygotes in GnomAdExome4 at 7 AR,Unknown gene
