The R810L likely pathogenic variant in the MYBPC3 gene has been previously published in association with HCM (Millat et al., 2010; Olivotto et al., 2011). Millat et al. (2010) originally reported R810L in an individual with HCM who also harbored a second variant (R1022P) in the MYBPC3 gene. Olivotto et al. (2011) identified R810L independently in an individual with HCM. The R810L variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). R810L is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Moreover, this substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. Lastly, a missense variant in the same residue (R810H) and missense variants in nearby residues (G805S, I807N, K811R) have been reported in Human Gene Mutation Database in association with HCM (Stenson et al., 2014), further supporting the functional importance of this residue and region of the protein.
