TMEM80 and rheumatoid arthritis: Among these genes, 59 RA-associated (e.g., CCBL2, SLC10A4, and PLEKHA1) and 19 SLE-associated genes (e.g., INPP5B, SKP1, and TMEM80) are not implied in the original GWASs of RA and SLE (Okada et al., 2014; Bentham et al., 2015), and are likely newly candidate associated genes for each disease.
