Labcorp Genetics (formerly Invitae), Labcorp RCV001061150 SCV001225883 uncertain significance Chédiak-Higashi syndrome 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces valine with leucine at codon 2266 of the LYST protein (p.Val2266Leu). The valine residue is weakly conserved and there is a small physicochemical difference between valine and leucine. This variant is present in population databases (rs530034435, ExAC 0.02%). This variant has not been reported in the literature in individuals affected with LYST-related conditions. 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. 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.
