This sequence change replaces arginine with glutamine at codon 313 of the RET protein (p.Arg313Gln). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs77702891, ExAC 0.1%) and has an allele count higher than expected for a pathogenic variant (PMID: 28166811). This variant has been reported in individuals affected with hirschsprung disease (PMID: 9090527, 22174939). ClinVar contains an entry for this variant (Variation ID: 13932). 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. 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.
