Contribution of interleukin 1beta and KM loci to alopecia areata

Hum Hered. 1999 Mar;49(2):85-9. doi: 10.1159/000022850.


Alopecia areata is a common skin disease in which proinflammatory cytokines such as IL-1beta may play a pathogenic role. In this study, we examined the distribution of genotypes of an IL-1beta single base change polymorphism at position +3953 in patients with alopecia areata. The distribution of immunoglobulin kappa light chain (KM) genotypes was similarly examined. The data obtained showed that the IL-1beta and KM loci act cooperatively to significantly increase susceptibility to alopecia areata.
