The potential usefulness of such drugs may vary between individuals, depending on α(2A)-adrenoceptor genetics, sympathetic tone and concomitant pathological conditions, such as cardiovascular disease and obesity.
Interactions were detected between ADRA2AC-1291G and ADRB2 Gln27-->Glu variants for obesity in African Americans and between ADRA2AC-1291G SNP and ADBR1 haplotype for obesity in whites.
The objective of the current study was to examine the potential impact of a C right arrow G substitution at position -1291 of the alpha2A-adrenergic receptor gene (ADRA2A) promoter on obesity and estimates of insulin, glucose, and lipid metabolism as well as circulating hormones, including salivary cortisol in 284 unrelated Swedish men born in 1944.
