At the same time, in view of previous reports of an increased risk of RA among Caucasians due to VDR gene polymorphisms and the FokI variant, an analysis of the association of four selected VDR gene polymorphisms (BsmI, FokI, ApaI, and TaqI) with susceptibility to RA in the Lithuanian population was conducted. The gene discussed is VDR; the disease is rheumatoid arthritis.
