Similarly, the branchpoint-site single-nucleotide polymorphisms rs17266594 and rs10516487 in the B cell scaffold protein with ankyrin repeats 1 (BANK1) gene have been testified to be associated with various autoimmune diseases including SLE (Guan et al., 2011), RA (Orozco et al., 2009), and SSc (Rueda et al., 2010). Here, BANK1 is linked to systemic lupus erythematosus.
