Labcorp Genetics (formerly Invitae), Labcorp RCV003614493 SCV004398780 uncertain significance Hyper-IgM syndrome type 2 2024-01-22 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 74 of the AICDA protein (p.Arg74Cys). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with AICDA-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
