TNF, IFNG, IL6, IL10 and TGFB1 gene polymorphisms in South and Southeast Brazil.

This study attempted to establish single nucleotide polymorphism frequencies of TNF, IL6, IFNG, IL10 and TGFB1 genes among healthy individuals from South and Southeast Brazil. The sample included 108 healthy individuals from South and 106 from Southeast Brazil. Polymerase chain reaction using sequence-specific primers genotyping was performed for these gene cytokines with Cytokine Genotyping Primers (One Lambda, Canoga Park, CA, USA).
