Background: Migraine is a common neurovascular disorder affected by various levels of neurotransmitters. Low histamine metabolism is also related with pathophysiology of migraine. As diamine oxidase (DAO) gene variants are linked with higher levels of histamine in migraine patients, we investigated the possible relationship of two variants rs2052129 and rs10156191of this gene with migraine risk in North Indian population. Methods: A case-control study for 250 migraine patients and 250 matched healthy controls was conducted by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: We found statistically significant differences in allelic frequencies of rs2052129 (p = .009, OR = 1.462; 95% CI: 1.098-1.947) and rs10156191 (p = .019, OR = 1.430; 95% CI: 1.060-1.928) variants in DAO gene. For rs1015691, we were able to show statistically significant association at all genotypic, dominant and allelic levels in both MA (for T allele, p = .020; OR = 1.662, 95% CI: 1.083-2.551) as well as in female subgroup (for T allele, p = .025, OR = 1.460; 95% CI: 1.049-2.033). But no such significant association was found in clinical sub grouping of migraine in rs2052129 as p > .05. However in gender analysis, protective effect of T allele in male migraine patients for rs2052129 (OR < 1) was found. Conclusions: Our findings clearly indicated that a female patient with rs10156191T allele and in MA subgroup showed an increased risk for migraine. Our data also indicated that rs2052129T variant showed a significant role in migraine susceptibility of this population.
