Description

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: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with JUP-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with serine at codon 162 of the JUP protein (p.Ala162Ser). The alanine residue is highly conserved and there is a moderate physicochemical difference between alanine and serine.
