Abstract:
Restriction fragment length polymorphisms (RFLPs) in the T cell receptor (TCR) alpha, beta, and gamma genes were analyzed in 61 scleroderma patients and 150 controls. An association was found between scleroderma and an 11.3-kb Pvu II fragment in the TCR gamma gene; this gene was found in 41.0% of the patients, compared with 21.7% of the controls (P less than 0.01, odds ratio = 2.50). There were no associations between scleroderma and the tested RFLPs in the TCR alpha or beta genes, and no RFLPs were found in the constant region of the TCR delta gene.
