title: Association of interleukin-19 gene polymorphisms with age.
abstract: We previously demonstrated a significant association of the interleukin-10 (IL-10) -819 T/C polymorphism with age. IL-19 stimulates the production of IL-10, and the IL-19 gene is located adjacent to the telomere side of the IL-10 gene. To explore the relationship between IL-19 single nucleotide polymorphisms (SNPs) and age, we genotyped 500 Japanese individuals (mean age: 56.7 years, range 19-100) for IL-19 Ser175Phe (T/C), -513 T/C, 1098 G/T (intron 1) and 5420 G/C (5'-untranslated region). Three of four SNPs (Ser175Phe, -513 T/C and 1098 G/T) exhibited a weak but significant association with age by chi-square test and logistic regression analysis (p <.05). IL-19 Ser175Phe was in linkage disequilibrium with -513 T/C and 1098 G/T, but not with IL-10 -819 T/C. These data suggest that IL-19 polymorphisms may be associated with age in a Japanese population.
