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 made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_noAF, Cadd, Eigen, phyloP100way_vertebrate, PrimateAI, PROVEAN, 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 male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Ambry Genetics

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2465A>G (p.H822R) alteration is located in exon 24 (coding exon 24) of the KIAA1033 gene. This alteration results from a A to G substitution at nucleotide position 2465, causing the histidine (H) at amino acid position 822 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
