Labcorp Genetics (formerly Invitae), Labcorp RCV003791933 SCV004586780 uncertain significance Tietz syndrome; Waardenburg syndrome type 2A; Melanoma, cutaneous malignant, susceptibility to, 8 2024-01-09 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 287 of the MITF protein (p.Glu287Lys). This variant is present in population databases (rs148242520, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MITF-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
