Abstract

Cyclin-dependent kinases 4/6 (CDK4/6) and D1-type cyclins (CCND1) can regulate the pro-inflammatory functions of various cytokines during the inflammatory response. This study investigated the association between CDK4/6-CCND1 variants and susceptibility in patients with Behcet's disease (BD). This case-control study enrolled 542 patients with BD and 754 healthy controls. Fourteen tagged single nucleotide polymorphisms (tag SNPs) of the CDK4/6-CCND1 gene were genotyped using the Sequenom MassARRAY system and iPLEX® Pro assay. The results indicated that the frequency of the CDK6 rs2282983 TT genotype was higher in the BD group than the control group (Pc = 0.040, OR = 1.408, 95% CI = 1.124-1.765), and CDK6 rs2282983 CT and rs42034 AG were negatively associated with BD (Pc = 3.647 × 10-4, OR = 0.598, 95% CI = 0.471-0.758; Pc = 0.039, OR = 0.626, 95% CI = 0.459-0.852, respectively). Furthermore, statistical analysis showed that CDK6 rs2282983 TT and CT genotypes were significantly associated with skin lesions in patients with BD (Pc = 0.042, OR = 1.436, 95% CI = 1.130-1.824; Pc = 0.001, OR = 0.594, 95% CI = 0.461-0.764, respectively). This study suggests that the CDK6 loci rs2282983 and rs42034 might confer genetic susceptibility to BD in a Han Chinese population, which could provide new insights into the pathogenesis of BD.
