Labcorp Genetics (formerly Invitae), Labcorp RCV001942529 SCV002133243 uncertain significance Severe combined immunodeficiency due to CORO1A deficiency 2021-09-24 criteria provided, single submitter clinical testing This sequence change replaces valine with methionine at codon 155 of the CORO1A protein (p.Val155Met). The valine residue is moderately conserved and there is a small physicochemical difference between valine and methionine. This variant is present in population databases (rs765244440, ExAC 0.002%). This variant has not been reported in the literature in individuals with CORO1A-related conditions. 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.
