rs1042713, also known as Arg16, G16R, and 16Arg>Gly, is a SNP in the adrenergic, beta-2-, surface receptor ADRB2 gene. The rs1042713(G) allele encodes the G/glycine form that is the more common one in most populations, while rs1042713(A) encodes the R/arginine residue at this position of the ADRB2 protein. A study of 1,182 young Scottish asthma patients (age, 3-22 years) concluded that rs1042713(A) alleles are significantly associated with "exacerbations" of their condition, regardless of treatment regimens (odds ratio 1.30, CI: 1.09-1.55, p=0.003). This didn't hold true for patients using inhalers less than once per day; and it was particularly true for those receiving daily inhaled long- or short-acting beta(2)-agonist treatment (OR, 1.64, CI: 1.22-2.20, p=.001). This may therefore indicate that regular inhalant use may be counter-productive in young asthma patients carrying one or especially two rs1042713(A) alleles.
