Labcorp Genetics (formerly Invitae), Labcorp RCV002048398 SCV002304290 uncertain significance Autosomal recessive severe congenital neutropenia due to G6PC3 deficiency 2021-03-08 criteria provided, single submitter clinical testing 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 serine 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 G6PC3-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with serine at codon 37 of the G6PC3 protein (p.Ile37Ser). The isoleucine residue is weakly conserved and there is a large physicochemical difference between isoleucine and serine.
