SNP variations in IL10, TNFα and TNFAIP3 genes in patients with dry eye syndrome and Sjogren’s syndrome

Background Cytokines are known to be key players in dry eye syndrome (DES) and Sjogren’s syndrome (SS) pathogenesis. In this study we compared single nucleotide polymorphism (SNP) variations in genes encoding cytokine levels among SS and DES patients in Israel.
