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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with EFHC1-related disease. This variant is present in population databases (rs749376467, ExAC 0.003%). This sequence change replaces alanine with proline at codon 590 of the EFHC1 protein (p.Ala590Pro). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and proline. -
