We evaluated the association between beta-adrenergic receptor genes (ADRB1 and ADRB2) polymorphism, cardiovascular risk, and acute coronary syndrome (ACS) in individuals from an Arab ethnicity. A total of 388 Qatari participants were assessed and genotyped for ADRB1 (rs1801252 & rs1801253) and ADRB2 (rs1042718 & rs1042713) polymorphisms using allele-specific PCR. Minor allele frequencies (MAF) in each single-nucleotide polymorphisms (SNPs) did not show statistically significant difference between cases and controls. A higher proportion of patients with ACS had homozygous minor alleles (GG) for rs1801253 (28.8% vs 17.1%; P =.019) compared with controls. Among cases with ACS, there was an association of minor allele frequency (G) for rs1801253 with severe coronary artery stenosis (0.485 vs 0.428; P =.04) than that of insignificant stenosis (<50% stenosis). There was a 3-fold increased risk of significant coronary stenosis in patients with diabetes mellitus (DM) and carrier of rs1801253 genotypes with dominant model (P =.01) and recessive model (P =.05). There is a possible synergic association between DM, carrier of ADRB1 (Arg389Gly) variants, and significant coronary artery stenosis among Arabs. Further prospective studies with larger sample sizes are warranted to support our findings. The Author(s) 2015.
