Labcorp Genetics (formerly Invitae), Labcorp RCV001348701 SCV001543011 uncertain significance Transcobalamin II deficiency 2022-08-16 criteria provided, single submitter clinical testing This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 150 of the TCN2 protein (p.Pro150Ala). This variant is present in population databases (rs776493564, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with TCN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1044456). 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 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.
