BANK1 and rheumatoid arthritis: This study analyzed salivary gland biopsies associating the allele frequencies with patients having ectopic germinal center structures and found a positive association with BANK1 polymorphisms as well as other genes, such as AICDA and BCL2. Association between variants of BANK1 and Sjogren’s syndrome was not replicated in a Chinese population [30] or any major GWAS of the disease [31], while BLK was indeed associated [30,31]; however, no study has analyzed the potential genetic role of BANK1 in the development of lymphoma in pSS or RA.
