Originally, a study of 477 Italian patients indicated that carriers of one or two rs4961(T) alleles were at 1.8x increased risk for hypertension (CI: 1.32-2.43). This study also indicated that carriers of the risk (T) allele responded better to diuretics and sodium-restricted diets, in that they tended to lower their blood pressure by ~10 mmHg points compared to rs4961(G;G) homozygotes similarly treated.[PMID 9149697]
Subsequent studies have tended to confirm this association, and to extend it to risk for heart disease. They also have tended to confirm that risk allele carriers respond better to therapy.
In a study of ~2200 Belgian patients, rs4961(T) carriers were generally at 2-3 fold higher rik for cardiovascular mortality and morbidity.[PMID 16043664]
In a study of ~1000 hypertensives followed for 10 years, rs4961(T) carriers responded better to low-dose diuretic therapy, as seen by a lower (almost halved) risk of combined myocardial infarction or stroke than if other antihypertensive therapies were used to achieve the same reduction in blood pressure.[PMID 11926892]
A SNP in another adducin gene, adducin 3 ADD3, may modify the risk of carrying an rs4961 risk allele. Carriers of an rs4961(T) allele who are also rs3731566(G;G) homozygotes have higher systolic and diastolic blood pressure, by about 8 mmHg, compared to if they have another rs3731566 genotype.[PMID 15716695]
