The p.R810L variant (also known as c.2429G>T), located in coding exon 25 of the MYBPC3 gene, results from a G to T substitution at nucleotide position 2429. The arginine at codon 810 is replaced by leucine, an amino acid with dissimilar properties. This variant has been reported in several unrelated individuals with hypertrophic cardiomyopathy (HCM), although in one case other alterations were also detected (Millat G et al. Eur J Med Genet 2010 Jul; 53(5):261-7; Olivotto I et al. J. Am. Coll. Cardiol. 2011 Aug; 58(8):839-48). Additionally, another variant affecting the same amino acid, p.R810H (c.2429G>A), has also been identified in multiple HCM cases, though some individuals were positive for other cardiac variants as well (Nanni et al. Biochem Biophys Res Commun. 2003;309(2):391-8; Maron et al. Am J Cardiol. 2011;107(4):604-8; Roncarati et al. Cell Physiol. 2011;226(11):2894-900). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the majority of available evidence to date, this variant is likely to be pathogenic.
