Labcorp Genetics (formerly Invitae), Labcorp RCV002015598 SCV002288400 uncertain significance Neu-Laxova syndrome 2 2021-06-20 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with PSAT1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces tyrosine with histidine at codon 279 of the PSAT1 protein (p.Tyr279His). The tyrosine residue is highly conserved and there is a moderate physicochemical difference between tyrosine and histidine. 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, 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.
