This sequence change replaces alanine with isoleucine at codon 60 of the FLVCR1 protein (p.Ala60Ile). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and isoleucine. 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 variant has not been reported in the literature in individuals with FLVCR1-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: Not Available; PolyPhen-2: Benign; Align-GVGD: Not Available). 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.
