	Caucasians vs. controls	Non-Caucasians vs. controls
Heterozygous 12-bp deletion (rs6148242)	p = 0.0071, OR = 2.357, CI: 1.256–4.426	p = 0.2325
Homozygous 12-bp deletion (rs6148242)	p = 0.0052, OR = 18.33, CI: 0.9869–340.6	p = 0.1754
Homozygous 1-bp insertion (rs5855273)	p<0.0001, OR = 44.10, CI: 2.549–762.8	p = 0.0368, OR = 4.513, CI: 1.036–19.66

Frequencies for each genotype are shown in Table 5. P: p-value. OR: odds ratio CI: 95% confidence intervals. Del: deletion. Ins: insertion. bp: base pair. Data were analyzed with contingency tables, χ-square, odds ratio and 95% confidence intervals.
