Another victory for DNA studies as described in the 23andMe Blog:
The study, the largest to date genome-wide association study on heart failure, also found shared genetic associations between heart failure and known heart failure risk factors such as hypertension, diabetes, and atrial fibrillation. The scientists also found strong associations with pulmonary conditions and musculoskeletal traits.
This study identified three variants associated with the condition in three different genes. One of those genes is involved in the regulation of muscles in the heart. Two of the genetic variants are newly associated with heart failure. The third has been previously identified. The three strongest associations were in the genes PITX2, ACTN2, and ABO.
