To further check if these variants differ by ethnicity, three single nucleotide polymorphisms (SNPs) (rs4379368, rs10504861and rs11172113) were genotyped here to find association with migraine susceptibility from North Indian population.
The meta-analysis confirmed the previous three genome-wide significant associated SNPs (rs2651899, rs10166942 and rs11172113</span>) to confer risk of migraine.
In a population-based genome-wide analysis including 5,122 migraineurs and 18,108 non-migraineurs, rs2651899 (1p36.32, PRDM16), rs10166942 (2q37.1, TRPM8) and rs11172113 (12q13.3, LRP1) were among the top seven associations (P < 5 × 10(-6)) with migraine.
To further replicate the GWAS findings, we investigated the 3 variants rs2651899 (1p36.32, PRDM16), rs10166942 (2q37.1, TRPM8), and rs11172113 (12q13.3, LRP1) for their association with migraine in the Chinese Han population.
We report significant influence of rs1835740, LRP1 rs11172113 and PRDM16 rs2651899 polymorphisms on migraine susceptibility in the North Indian population.
Genetic polymorphisms all previously reported as showing a significant correlation with AAA with functional effects on the expression or function were determined by analysis of the genomic DNA, including angiotensin 1 receptor (rs5186), interleukin-10 (IL-10; rs1800896), methyl-tetrahydrofolate reductase (rs1801133), low-density lipoprotein receptor-related protein 1 (LRP1; rs1466535), angiotensin-converting enzyme (rs1799752), and several matrix metalloproteinase 9 (MMP-9) single nucleotide polymorphisms.
No associations were seen for either rs1466535 or the 12q13.3 locus in independent association studies of coronary artery disease, blood pressure, diabetes, or hyperlipidaemia, suggesting that this locus is specific to AAA.
An association between rs1466535 low density lipoprotein receptor-related protein 1 (LRP1) gene polymorphism and abdominal aortic aneurysm (AAA) was recently demonstrated.
