The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and serine. This variant is present in population databases (rs148609143, ExAC 0.03%). This variant has not been reported in the literature in individuals with DHCR7-related conditions. ClinVar contains an entry for this variant (Variation ID: 445437). 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.
