Labcorp Genetics (formerly Invitae), Labcorp RCV001309732 SCV001499240 uncertain significance Hyper-IgM syndrome type 2 2020-03-25 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but 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. This variant has not been reported in the literature in individuals with AICDA-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces histidine with arginine at codon 93 of the AICDA protein (p.His93Arg). The histidine residue is moderately conserved and there is a small physicochemical difference between histidine and arginine.
