In the present study, we evaluated the association of TLR4 and CD14 polymorphisms, i.e. C1196T and C-260T, respectively, with ischemic stroke (n?=?700), its subtypes and hemorrhagic stroke (n?=?300) in a South Indian population from Telangana. The genotypes were determined using PCR?RFLP, and the strength of association between genotypes and stroke was determined by odds ratio with 95% confidence interval (CI) and chi-square analysis. The results revealed a lack of association for TLR4 variant with ischemic stroke and hemorrhagic stroke, although a significant association was observed with the subtypes extracranial large artery (p?=?0.008), other determined aetiology (p?=?0.03) and undetermined aetiology (p?=?0.01). Investigations on the variant of CD14 gene revealed negative association among ischemic stroke patients; however, a significant association was observed for hemorrhagic stroke following dominant and recessive genotypic model (p?=?0.05, p?=?0.02). Among ischemic stroke subtype, a significant association was observed with intracranial large artery, extracranial large artery, other determined aetiology and undetermined aetiology form of stroke (p?<?0.01). Further, analysis of the CD14 variant between the two major stroke types revealed a significant difference in genotype distribution following the co-dominant genotypic model (p?=?0.01). ? 2017, Springer Science+Business Media, LLC.
