| Invitae | RCV003763762 | SCV001213165 | uncertain significance | Autosomal recessive hyper-IgE syndrome | 2020-09-01 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid with lysine at codon 247 of the DOCK8 protein (p.Glu247Lys). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and lysine. 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. 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 lysine 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. This variant has not been reported in the literature in individuals with DOCK8-related conditions. This variant is present in population databases (rs780285682, ExAC 0.002%). |
