Invitae RCV003763901 SCV001403982 uncertain significance Autosomal recessive hyper-IgE syndrome 2019-10-16 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with DOCK8-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with threonine at codon 470 of the DOCK8 protein (p.Ser470Thr). The serine residue is moderately conserved and there is a small physicochemical difference between serine and threonine. 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 threonine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
