Sjogren's syndrome (SS), a chronic autoimmune disease, typically causes or involves inflammation in the salivary and lacrimal glands. Although recent genetic association studies have contributed to the discovery of SS susceptible genes, few studies have reported on the Korean population. Here, we did a genetic association study of SS in Korean patients using whole-exome sequencing data of 15 patients and 100 healthy controls. In addition to confirming previously described SS susceptibility loci MSH5 (p = 1.67 × 10-5) and RELN (p = 4.91 × 10-6), we also validated PRAMEF13 (p = 2.28 × 10-5), TARBP1 (p = 1.87 × 10-5), UGT2B28 (p = 1.33 × 10-5), TRBV5-6 (p = 2.27 × 10-5) and NAPB (p = 3.73 × 10-5) as novel susceptibility loci for SS. Furthermore, we identified UGT2B28, TARBP1 and PRAMEF13 as associated with human immune function. These findings may provide useful insight into to the pathways and pathogenesis contributing to SS susceptibility in the Korean population.
