This sequence change replaces aspartic acid with asparagine at codon 1111 of the LRP4 protein (p.Asp1111Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs770071302, ExAC 0.001%). This variant has not been reported in the literature in individuals affected with LRP4-related conditions. 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. 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. -
