Genes affected
WDR62 (HGNC:24502): (WD repeat domain 62) This gene is proposed to play a role in cerebral cortical development. Mutations in this gene have been associated with microencephaly, cortical malformations, and cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2011]
THAP8 (HGNC:23191): (THAP domain containing 8) Predicted to enable DNA binding activity and metal ion binding activity. [provided by Alliance of Genome Resources, Apr 2022]

This variant has not been reported in the literature in individuals affected with WDR62-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant is present in population databases (rs759466940, ExAC 0.08%). This sequence change replaces tyrosine with cysteine at codon 9 of the WDR62 protein (p.Tyr9Cys). The tyrosine residue is weakly conserved and there is a large physicochemical difference between tyrosine and cysteine. -
