Interpretive Data
Elevated RNA polymerase III IgG antibodies are found primarily in a subset of systemic sclerosis (SSc) patients who are typically negative for anti-centromere and anti-Scl-70 antibodies, and which may be predictive of increased risk for skin involvement and hypertensive renal failure associated with the diffuse cutaneous form of scleroderma.
