This sequence change replaces arginine with cysteine at codon 571 of the ENG protein (p.Arg571Cys). The arginine residue is moderately conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs764262721, ExAC 0.02%). This variant has been observed in an individual affected with juvenile polyposis (PMID: 16287957). ClinVar contains an entry for this variant (Variation ID: 282707). 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: Probably 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.
