type-2 diabetes.

each C at rs2237892 increased the odds of type 2 diabetes by 1.4 times, compared to the TT genotype. It’s important to note, however, that the C version is actually pretty common.

In Asian populations, the C version of rs2237892 increased a person’s odds of type 2 diabetes by 1.42 times compared to people with TT. But because about 50% of the Asian population is actually CT at this SNP, it could be viewed that CC has 1.3 times the odds compared to typical, while TT has 0.61 times the typical odds.

In European populations, about 85% of people are CC. This means that the results of Yasuda et al really show that compared to most Europeans, people with CT at rs2237892 have 0.78 times the typical odds of developing type 2 diabetes, and the odds for people with TT are 0.52 times typical.
