Labcorp Genetics (formerly Invitae), Labcorp RCV002598567 SCV003487378 uncertain significance Chédiak-Higashi syndrome 2022-07-14 criteria provided, single submitter clinical testing 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. 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. This variant has not been reported in the literature in individuals affected with LYST-related conditions. This variant is present in population databases (rs773927032, gnomAD 0.006%). This sequence change replaces valine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 2259 of the LYST protein (p.Val2259Phe).
