This sequence change replaces asparagine with tyrosine at codon 1814 of the TUBGCP6 protein (p.Asn1814Tyr). The asparagine residue is moderately conserved and there is a large physicochemical difference between asparagine and tyrosine. This variant is present in population databases (rs762167154, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with TUBGCP6-related conditions. 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"). 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. -
