WebFeb 16, 2012 · TTN, the gene encoding the sarcomere protein titin, has been insufficiently analyzed for cardiomyopathy mutations because of its enormous size. Methods: We analyzed TTN in 312 subjects with dilated cardiomyopathy, 231 subjects with hypertrophic cardiomyopathy, and 249 controls by using next-generation or dideoxy sequencing. WebVariants in genes that lack known links to AF may indirectly promote an arrhythmogenic substrate by affecting threshold levels for exercise-induced myocardial damage and remodelling responses, or by effects on AF-associated co-morbidities, sinus node function, and autonomic nervous system tone.

WebJun 20, 2024 · Their study showed having a titin truncating mutation – a kind of premature stop sign in the gene that results in a shorter protein – puts people at significantly higher risk for developing cardiomyopathy. People with cardiomyopathies are at greater risk for heart failure or irregular heartbeats called arrhythmias than the general public. WebMutations associated with dilated cardiomyopathy were overrepresented in the titin A-band but were absent from the Z-disk and M-band regions of titin (P≤0.01 for all comparisons). thermomètre auchan

WebJan 15, 2014 · Familial restrictive cardiomyopathy (RCM) caused by a single gene mutation is the least common of the inherited cardiomyopathies. Only a few RCM-causing mutations have been described. Most mutations causing RCM are located in sarcomere protein genes which also cause hypertrophic cardiomyopathy (HCM). WebDSP gene mutations can also cause a potentially life-threatening form of heart disease called arrhythmogenic right ventricular cardiomyopathy (ARVC) without abnormalities of the skin and hair.
