Ethnic differences in the distribution of interleukin-6 polymorphisms among three brazilian ethnic groups

Polymorphisms in the interleukin-6 promoter region have been associated with diseases. In this study we investigated the 634G/C and 174G/C IL-6 promoter polymorphisms in three Brazilian ethnic groups. We verified that the allele frequencies of the two polymorphisms and haplo- type frequencies varied significantly between the populations.
