This variant is not present in population databases (ExAC no frequency). This sequence change replaces phenylalanine with leucine at codon 1806 of the TUBGCP6 protein (p.Phe1806Leu). The phenylalanine residue is moderately conserved and there is a small physicochemical difference between phenylalanine and leucine. This variant has not been reported in the literature in individuals with TUBGCP6-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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). -
