Degree of hypertrophy (A), degree of left ventricular outflow tract obstruction (B), and age at diagnosis (C) for genotyped subjects. Genotyped patients with hypertrophic cardiomyopathy are grouped on the X-axis as hosting as hosting no putative mutation (genotype negative), hosting a myofilament mutation (myofilament-HCM), a MLP-mutation or a TCAP-mutation. Unless otherwise noted, all pair wise comparisons are not statistically significant. *p < 0.05 compared to all other groups.
