Abstract

The H19 (rs2839698, rs3741219) and HOTAIR (rs920778) polymorphisms were related to many kinds of cancers. However, these polymorphisms have been scarcely explored in different autoimmune diseases. Here, we aimed to examine the association of the polymorphisms with susceptibility to or protection against systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and primary Sjögren's syndrome (pSS) among Chinese Han patients. We conducted a case-control study including 800 patients (300 with SLE, 350 with RA, and 150 with pSS) and 350 healthy control individuals. The polymorphisms were specified from genomic DNA using TaqMan genotyping assay on a 7300 real-time reverse transcription polymerase chain reaction system. H19 rs2839698 was not associated with SLE susceptibility and was not associated with RA and pSS, respectively (P > 0.05). Similarly, we did not find significant differences of allele or genotype frequencies between SLE, RA, and pSS patients and healthy controls for H19 gene rs3741219 polymorphism (P > 0.05). In addition, no significant evidence was detected for the relationship of HOTAIR rs920778 polymorphism with risk of these diseases. Our results suggested that H19 rs2839698, rs3741219, and HOTAIR rs920778 polymorphisms may not be involved in the genetic background of SLE, RA, and pSS in Chinese.
