SNPs with opposite risk profiles in two autoimmune classes.

SNPs such that one allele predisposes an individual to one class of autoimmune diseases (RA and AS), but protects from the other class (MS and ATD) or vice versa. Each SNP in this set has a significant association (p<0.05) with at least one disease per class. The SNPs where the minor allele has a negative odds-ratio (protective) are underlined to show the separation more clearly.
