Abstract: Background: Inherited genetic variations offer a possible explanation for the observed peculiarities of stroke in sub - Saharan African populations. Interleukin–6 polymorphisms have been previously associated with ischemic stroke in some non-African populations. Aim: Herein we investigated, for the first time, the association of genetic polymorphisms of IL-6, CDKN2ACDKN2B and other genes with ischemic stroke among indigenous West African participants in the Stroke Investigative Research and Education Network (SIREN) Study. Methods: Twenty-three previously identified single nucleotide polymorphisms (SNPs) in 14 genes of relevance to the neurobiology of ischemic stroke were investigated. Logistic regression models adjusting for known cardiovascular disease risk factorswere constructed to assess the associations of the 23 SNPs in rigorously phenotyped cases (N=429) of ischemic stroke (Men=198;Women=231) and stroke– free (N=483) controls (Men= 236; Women = 247). Results: Interleukin-6 (IL6) rs1800796 (C minor allele; frequency:West Africans=8.6%) was significantly associated with ischemic stroke in men (OR = 2.006, 95% CI = [1.065, 3.777], p = 0.031) with hypertension in the model but not in women. In addition, rs2383207 in CDKN2A/CDKN2B (minor allele A with frequency:West Africans= 1.7%) was also associated with ischemic stroke inmen (OR=2.550, 95% CI=[1.027, 6.331], p=0.044) with primary covariates in the model, but not inwomen. Polymorphisms in other genes did not showsignificant association with ischemic stroke.
