Abstract

Objective. To evaluate the role of the T cell receptor β chain locus TCRB in genetic susceptibility to rheumatoid arthritis (RA). Methods. Twenty‐eight multiplex RA families were recruited from 3 rheumatology outpatient departments. All members were genotyped for a highly informative microsatellite (V β6.7), a V β12.2 SSCP marker, and a biallelic Cβ restriction fragment length polymorphism. Data were analyzed by the SIBPAL program to assess identity‐by‐descent in affected sib‐pairs. Results. Using the V β12.2 marker, there was suggestive evidence of increased sib‐pair sharing (P = 0.005) in affected offspring (a P value of 0.001 is generally taken to establish linkage). Data for V β6.7 and Cβ yielded significance levels of 0.06 and 0.19, respectively. Conclusion. These data suggest that a gene in or linked to the TCRB complex may confer genetic susceptibility to RA in these families. Confirmation in a larger panel of families is required.
