^aFrequencies from NCBI dbSNP database 2013. The study sample and published dbSNP database are of similar populations: rs17492553—χ² (2) = 3.88, P = 0.14; rs34160967—Fisher’s exact (P = 0.44).

^b,cFrom Fisher’s exact testing, the study sample distribution for rs34160967 was different than in adults recruited in Japan (Shigemura et al. 2009; P < 0.01) and not different from those recruited in France (Raliou et al. 2009b; P = 0.13).
