title: Transferrin C subtypes and rheumatoid arthritis.
abstract: Transferrin C subtypes were studied in patients with rheumatoid arthritis (RA) and controls. A significant association was found between the C2 type and RA. This association concerned mainly male patients and patients with a family history of polyarthritis. The results were discussed in relation to previous studies of the role of oxygen free radicals in the pathogenesis of RA and to a recently proposed hypothesis that the TfC2 gene confers an increased risk for cellular damage by hydroxyl radicals.
