Anti-SSA autoantibodies (also called anti-Ro, or the combination anti-SSA/Ro or anti Ro/SSA autoantibodies) are anti-nuclear autoantibodies that are associated with among many autoimmune diseases, such as systemic lupus erythematosus (SLE), SS/SLE overlap syndrome, subacute cutaneous LE (SCLE), neonatal lupus and primary biliary cirrhosis.[1] Also, they are often present in Sjögren's syndrome.[2] [3]
Presence of Anti-SSA/Ro in pregnant women with SLE is associated with an increased risk of neonatal lupus erythematosus in the child.[4]
Approximately only 0.1 to 0.5 percent of the general population has the antibody.
