Description

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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals with MC1R-related conditions. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This sequence change replaces alanine with tyrosine at codon 222 of the MC1R protein (p.Ala222Tyr). The alanine residue is moderately conserved and there is a moderate physicochemical difference between alanine and tyrosine.
