The TNFSF15 CCC haplotype frequency was discovered to be significantly increased in scleritis cases without as well as with systemic diseases, as compared with healthy volunteers (Pc = 0.039, OR = 1.579, 95% CI = 1.096–2.274; Pc = 0.027, OR = 2.496, 95% CI = 1.229–5.067, respectively) (Table 6). Here, TNFSF15 is linked to scleritis.
