The observed differences in the cytokine production among individuals can be, at least, explained by genetic polymorphisms like single nucleotide polymorphism (SNP). In 181 unrelated healthy Brazilian individuals from Rio de Janeiro City, we investigated the polymorphisms of cytokine genes encoding Tumor Necrosis Factor-alpha (TNFA), Transforming Growth Factor beta (TGFB), Interleukin (IL)-10, IL-6, and Interferon-gamma (IFNG). Polymerase chain reaction using sequence-specific primers genotyping was performed for these gene cytokines using the avaiable comercial kit CytGen (One Lambda Inc., CA, USA). Eight polymorphisms were tested: TNF-a (-308G/A); TGF-b (códon 10C/T, códon 25C/G); IL-10 (-1082A/G, -819T/C, -592A/C); IL-6 (-174G/C) and IFN-g (+874T/A). Chi-square test was used for comparisons. Observed data were compared to three other populations from different regions of Brazil (São Paulo, Paraná and Bahia) and three populations of other countries (Italy, Slovakia and North American Blacks). Our analysis from Rio de Janeiro population showed that the alleles frequencies in IL-10, IL-6 and IFN-g are unevenly distributed among Whites, Blacks and Mulatos (p
