Polymorphisms within the interleukin-10 receptor cDNA gene (IL10R) in Japanese patients with systemic lupus erythematosus

Objective. To assess the association between polymorphisms within the inter leukin-10 receptor cDNA gene (IL10R) and systemic erythematosus (SLE) in Ja panese people. Method. We examined the IL-10 receptor genotype of 109 SLE patients and 102 healthy subjects by the reverse transcription-polymerase chain reaction-re striction fragment length polymorphism (RT-PCR-RFLP) method. Results. There was no difference in the IL10R genotype frequencies of these two groups. Conclusion. The IL10R genotype does not determine susceptibility to SLE in Japanese people.
