TNFSF15 and scleritis: In addition, a study on the genotypes of TNF-α-related genes in Chinese Han patients with scleritis found that specific haplotypes in TNFAIP3 (TNF-α-induced protein 3), TNFSF4 (TNF-αreceptor superfamily member 4), and TNFSF15 might be the risk or protective factors of scleritis in Chinese Han [45].
