Labcorp Genetics (formerly Invitae), Labcorp RCV002001078 SCV002276059 uncertain significance Severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-negative, due to adenosine deaminase deficiency 2021-11-01 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 140 of the ADA protein (p.Gly140Arg). This variant is present in population databases (rs746917604, gnomAD 0.001%). This variant has not been reported in the literature in individuals affected with ADA-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ADA 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.
