Labcorp Genetics (formerly Invitae), Labcorp RCV001245399 SCV001418684 uncertain significance X-linked immunodeficiency with magnesium defect, Epstein-Barr virus infection and neoplasia 2019-10-09 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 (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. This variant has not been reported in the literature in individuals with MAGT1-related conditions. This variant is present in population databases (rs782261030, ExAC 0.002%). This sequence change replaces arginine with cysteine at codon 36 of the MAGT1 protein (p.Arg36Cys). The arginine residue is weakly conserved and there is a large physicochemical difference between arginine and cysteine.
