Susceptibility
|
to atrial cardiomyopathy with heart block (see ATFB1A) to essential hypertension in men to Tetralogy of Fallot |
Variant & Polymorphism
other
| somatic mutations in atrial cardiomyopathy with heart block |
|
polymorphisms increasing the risk of essential hypertension in men |
|
A96S mutation, the aberrant extravascular localization of renin-secreting cells in the kidney likely impairs the pressure-mediated inhibition of renin secretion, and is associated to essential hypertension |

Candidate gene
