The maximal force a muscle can exert depends on its length,which has been explained by the sliding filament theory on the sarcomere level.1 A longer muscle can act over a greater range of motion and has more sarcomere...

Skeletal and cardiac muscles are striated myofibers that contain highly organized sarcomeres for muscle contraction.Recent studies revealed that Smyd1,a lysine methyltransferase,plays a key role in sarcomere assembly ...
ObjectiveTo seek potential pathogenic variants in sarcomere genes in arrhythmogenic cardiomyopathy(ACM)and describe the characteristics.Methods and Results We performed targeted sequencing of 14sarcomere genes in 118 ...

Pediatric restrictive cardiomyopathy is rare and most commonly idiopathic in origin. Here, we applied a candi- date gene approach and identified a missense mutation in the cardiac troponin I gene in a 12-year-old Chin...
