Description

This variant has not been reported in the literature in individuals affected with FLCN-related conditions. 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 is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with tyrosine at codon 552 of the FLCN protein (p.Phe552Tyr). The phenylalanine residue is highly conserved and there is a small physicochemical difference between phenylalanine and tyrosine.
