Okada et al. [12] performed a genome-wide association study (GWAS) on RA and identified 42 novel risk single nucleotide polymorphisms (SNPs), including rs909685 (located in SYNGR1), rs110896379 (located in UBE2L3-YDJC), and rs793108 (located in ZNF438). This evidence concerns the gene ZNF438 and rheumatoid arthritis.
