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]

WASHC4 Gene-Disease associations (from GenCC):

• autosomal recessive non-syndromic intellectual disability

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet
• intellectual disability, autosomal recessive 43

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics
• schizophrenia

ACMG classification

Our verdict: Likely_benign. The variant received -1 ACMG points.

• PP3: Multiple lines of computational evidence support a deleterious effect 7: BayesDel_noAF, Cadd, Eigen, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
• BP4: Computational evidence support a benign effect (MetaRNN=0.2723574).
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.0000985 (15/152308) while in subpopulation SAS AF = 0.00104 (5/4830). AF 95% confidence interval is 0.000408. There are 0 homozygotes in GnomAd4. There are 8 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
