Labcorp Genetics (formerly Invitae), Labcorp RCV001365773 SCV001562054 uncertain significance Tyrosinemia type II 2021-08-27 criteria provided, single submitter clinical testing This sequence change replaces serine with phenylalanine at codon 75 of the TAT protein (p.Ser75Phe). The serine residue is weakly conserved and there is a large physicochemical difference between serine and phenylalanine. This variant is present in population databases (rs773076331, ExAC 0.1%). This variant has not been reported in the literature in individuals affected with TAT-related conditions. 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: "Deleterious"; 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.
