Labcorp Genetics (formerly Invitae), Labcorp RCV000688468 SCV000816080 uncertain significance Haim-Munk syndrome; Periodontitis, aggressive 1; Papillon-Lefèvre syndrome 2018-04-17 criteria provided, single submitter clinical testing This sequence change replaces tyrosine with histidine at codon 99 of the CTSC protein (p.Tyr99His). The¬†tyrosine¬†residue is highly conserved and there is a moderate physicochemical difference between¬†tyrosine¬†and histidine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with CTSC-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; 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.
