WebAn integral element of myofibril maturation is sarcomeric isoform switching, in which several sarcomere components switch from a fetal to an adult isoform due to transcriptional changes or alternative splicing. In rodents, among the most well-known is the myosin heavy chain (Myh) switch from fetal Myh7 to adult Myh6. WebThe β isoform of myosin heavy chain, the major isoform in the human ventricle and in slow-twitch skeletal fibers, is encoded by MYH7. This gene appears to be the most commonly mutated HCM gene, and hot spots for mutations have been identified. 68,114,126,128,129 Most of the mutations are missense mutations located either in the head or in the ...
