Statistics from

A case–control linkage disequilibrium study in a Japanese population showed that the peptidyl arginine deiminase type 4 (PADI4) is a susceptibility locus for rheumatoid arthritis (p<0.05).1 Ikari et al2 also showed an association of the PADI4 haplotype with rheumatoid arthritis in an independent Japanese study, but the relationship between the level of anti-cyclic citrullinated peptide (anti-CCP) antibodies and the haplotype has not been shown. Barton et al3,4 and Caponi et al5 could not validate the association in the UK or Caucasian French populations. The purpose of this study was to ascertain the relationship between levels of anti-CCP antibodies and PADI4 allele frequencies in a …
