What is Sarcomeric hypertrophic cardiomyopathy?

Familial hypertrophic cardiomyopathy (HCM) is now known to be a heritable form of cardiac hypertrophy caused by mutations in genes encoding sarcomeric proteins. Affecting 1/500 of the population, HCM is the most common identified cause of sudden death in young people (1).

What gene causes hypertrophic cardiomyopathy?

Mutations in one of several genes can cause familial hypertrophic cardiomyopathy; the most commonly involved genes are MYH7, MYBPC3, TNNT2, and TNNI3. Other genes, including some that have not been identified, may also be involved in this condition.

What protein is affected in hypertrophic cardiomyopathy?

Mutations in the cardiac myosin binding protein-C gene on chromosome 11 cause familial hypertrophic cardiomyopathy.

How serious is hypertrophic cardiomyopathy?

As HCM progresses, it can cause other health problems. People with HCM are at higher risk for developing atrial fibrillation, which can lead to blood clots, stroke and other heart-related complications. HCM may also lead to heart failure. It can also lead to sudden cardiac arrest, but this is rare.

Can you live a long life with hypertrophic cardiomyopathy?

Hypertrophic cardiomyopathy (HCM) is consistent with survival to normal life expectancy, including particularly advanced age into the tenth decade of life, with demise ultimately largely unrelated to this disease, according to a study being presented Nov.

What is the prognosis for hypertrophic cardiomyopathy?

Conclusion: HCM has a relatively benign prognosis (1% cardiac annual mortality) that is 2-4 times less than previously thought. These findings might have important consequences for risk assessment in individual patients. Echocardiography is obligatory to determine the presence, and extent of myocardial hypertrophy.

Is hypertrophic cardiomyopathy a death sentence?

“HCM is widely misperceived as a fatal condition, but a diagnosis of HCM is not a diagnosis of sudden cardiac death. We now have effective treatments to help most patients manage the condition, although it remains the most common cause of sudden death in the young and in competitive athletes,” said Bernard J.

Can a mutation in ANKRD1 cause hypertrophic cardiomyopathy?

Mutations in ANKRD1 have been associated with dilated cardiomyopathy, two of which result in altered binding with TLN1 and FHL2. Mutations in ANKRD1 have also been associated with hypertrophic cardiomyopathy, and have shown to increase binding of CARP to Titin and MYPN.

What kind of mutations are found in ANKRD1?

ANKRD1 is a novel DCM gene, with mutations present in 1.9% of DCM patients. The ANKRD1 mutations may cause DCM Data show that ANKRD1 is a short-lived protein whose levels are tightly regulated by the 26S proteasome.

What is the role of ANKRD1 in heart failure?

ANKRD1 mRNA levels correlate with patient platinum sensitivity, thus ANKRD1 associates with platinum-based chemotherapy treatment outcome in ovarian adenocarcinoma patients. CARP and mRNA expression has been shown to be upregulated in left ventricles of heart failure patients.

Are there any mutations in the ankyrin repeat domain 1 gene?

ANKRD1 is a novel DCM gene, with mutations present in 1.9% of DCM patients. The ANKRD1 mutations may cause DCM. Data show that ANKRD1 is a short-lived protein whose levels are tightly regulated by the 26S proteasome.
