rs5051 is a SNP in the promoter of the angiotensin AGT gene, and presumably due to it's tight linkage with rs699, the rs5051(T) allele - as oriented to the dbSNP entry, not as published - has been associated with increased risk for hypertension and complications thereof. rs699(T) is associated with higher plasma angiotensinogen levels, and therefore the increased risk of essential hypertension. The frequency of the rs699(T) allele is also generally higher in African populations compared to Caucasian populations, correlating to the higher incidence of hypertension in African population.[PMID 15077204]
rs5051(T;T) homozygotes have been reported to be at increased risk for Crohn's disease, as based on one cohort of ~350 Australian patients. The odds ratio was 2.38 (CI: 1.32-4.32, p=0.007). The authors suggest that association of an AGT SNP with Crohn's disease supports a potential role for angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists in the treatment of Crohn's disease.[PMID 17047091]
