We have previously reported a genetic susceptibility to a scleroderma-like disorder in a group of workers exposed to polyvinyl chloride and this susceptibility could be mapped to the major histocompatibility complex area of the 6th chromosome. To date no genetic studies have been reported comparing affected with unaffected workers. We report such data and discuss it in the light of our previous findings in vinyl chloride exposed patients and in patients with classical scleroderma. Our results suggest that susceptibility to this disorder is increased in the presence of HLA-DR5 or of a gene in linkage disequilibrium with it and an antigen associated with the haplotype A1 B8, while DR3 favours progression of the disease.
