Rs2231137

rs2231137, also known as Val12Met, is a SNP in the ATP-binding cassette, sub-family G (WHITE), member 2 ABCG2 gene. The (G) allele encodes the Val.

In a study of incident ischemic stroke during 14 years of follow-up in a population-based study of older adults known as the Cardiovascular Health Study (CHS), rs2231137 was associated with stroke in both white (hazard ratio, 1.46, CI: 1.05 - 2.03) and black (hazard ratio, 3.59, CI, 1.11 - 11.6) participants. The risk of ischemic stroke was higher in Val allele homozygotes than in Met allele carriers. The adjusted hazard ratio for Val allele homozygotes, compared with Met allele carriers, was 1.50 (90% CI, 1.06 to 2.12) in whites and 3.62 (90% CI, 1.11 to 11.9) in black participants (Table 4).
