Haplotype a	Controls (n = 214) No. (%)	Cases (n = 93) No. (%)	OR (95% CI)	P	P c
C A C	202.00 (47.2)	78.00 (41.9)	0.81 (0.57–1.14)	0.229	NS
C A T	55.00 (12.9)	29.00 (15.6)	1.25 (0.77–2.04)	0.364	NS

P _c, Bonferroni corrected P; NS, not significant.

^a The allelic sequence in the haplotypes is in the following order: rs7069102, rs3818292, rs4746720.
