Variation in Toll-like receptor 4 and susceptibility to group A meningococcal meningitis in Gambian children.

Abstract

Meningitis is an important cause of childhood mortality in sub-Saharan Africa. A case-control study investigating the role of the Toll-like receptor 4 gene in host susceptibility to Group A Neisseria meningitidis meningitis was conducted in 524 Gambian children. There was no association between a functional Toll-like receptor 4 gene polymorphism and meningitis, suggesting that this variant is not a major determinant of disease in this population.
