Open Access Abstract Peptidylarginine deiminase type 4 PADI4 genotypes were shown to influence susceptibility to rheumatoid arthritis RA in the Japanese population. Such an association could not previously be confirmed in different European populations. In the present study we analysed exons 2-4 of PADI4 in 102 German RA patients and 102 healthy individuals to study the influence of PADI4 variability on RA susceptibility by means of haplotypespecific DNA sequencing. Analyses of the influence of PADI4 and HLA-DRB1 genotypes on disease activity and on levels of anti-cyclic citrullinated peptide antibodies were performed. Comparing the frequencies of PADI4 haplotype 4 padi4_89 G padi4_90 T padi4_92 G padi4_94 T padi4_104 C padi4_95 G padi4_96 T .
