Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disease. While ≈50% of patients with HCM carry a sarcomere gene mutation (sarcomere mutation-positive, HCM A proteomics screen was performed in cardiac tissue from 39 HCM In all HCM patient samples, we found lower levels of metabolic pathway proteins and higher levels of extracellular matrix proteins. Levels of total and detyrosinated α-tubulin were markedly higher in HCM Our findings indicate that microtubules and especially its detyrosination contribute to the pathomechanism of patients with HCM Show less
