This present report takes our understanding a significant step forward by questioning whether genetic drift in distinct colonies of the same inbred strains of mice has an impact on the parity between data published by different laboratories. In the previous issue of Arthritis Research Therapy Farkas and colleagues 1 compare a large number of colonies of the widely used BALB c inbred mouse strain the authors communicate largely good news that substrains vary only modestly in phenotype and the incidence and severity of arthritis. Confidence in data derived from studying the mechanisms of immunopathology in patients with rheumatoid arthritis RA or ankylosing spondylitis is undermined by many variables. One is the genetic diversity of patients in a single cohort or diversity between cohorts studied in different laboratories. Despite a strong association between the expression of certain HLA DR alleles and RA many additional major histocompatibility .
