Labcorp Genetics (formerly Invitae), Labcorp RCV003059520 SCV003339550 uncertain significance ALG12-congenital disorder of glycosylation 2022-09-01 criteria provided, single submitter clinical testing This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 289 of the ALG12 protein (p.His289Arg). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ALG12-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 arginine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
