title: [Identification of a novel candidate gene KLRC1 within the putative susceptibility locus for systemic lupus erythematosus at 12p12.3-13.2 in a Chinese cohort].
abstract: OBJECTIVE
  To identify the candidate genes within the putative susceptibility locus for systemic lupus erythematosus (SLE) at 12p12.3-13.2.
  
  
  METHODS
  KLRC1 was selected as the candidate gene according to the results of previous gene chip studies. TaqMan real-time quantitative PCR was performed for detecting KLRC1 mRNA expression in 55 SLE patients and 30 controls.
  
  
  CONCLUSIONS
  KLRC1 mRNA expression was significantly higher in the mononuclear cells and T cells of SLE patients than in the healthy controls (P<0.01), but showed no significant difference in the B cells. No obvious correlation was found between the SLE disease activity index (SLEDAI) and KLRC1expression level, suggesting that KLRC1 can be a probable candidate gene for SLE on 12p12.3-13.2, but which is not associated with the disease activity.
