However, there were also different results: polymorphisms in NLRP1 rs6502867 T/C were shown not related to the risk of developing RA in Chinese Singaporeans (107), and another study also showed that genetic polymorphisms in NLRP1 rs6502867 C/T and rs878329 C/G were not associated with RA (108). This evidence concerns the gene NLRP1 and rheumatoid arthritis.
