Labcorp Genetics (formerly Invitae), Labcorp RCV001937262 SCV002131901 uncertain significance Transcobalamin II deficiency 2022-07-01 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 1363952). This variant has not been reported in the literature in individuals affected with TCN2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 268 of the TCN2 protein (p.Leu268Phe). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
