The T260I variant has been published in a patient diagnosed with hypertrophic cardiomyopathy (HCM) (Pandit et al., 2007) with limited evidence. The T260I variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The T260I variant 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. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. Missense variants in the same (T260R) and in nearby residues (R256S, S257L, S259P/T/F, P261S/A/T/R/L, N262K/K) have been reported in the Human Gene Mutation Database in association with Noonan syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein. In summary, this variant is likely pathogenic.
