Those with a history of GAVE compared with those without a history of GAVE were more frequently ANA positive (98.6% vs 94.9%, p = 0.019) with a speckled rather than a homogenous pattern (39.7% vs 29.3%, p = 0.003 and 9.6% vs 22.2%, p < 0.001 respectively), negative for antitopoisomerase-1 (Scl-70), U1 small nuclear ribonucleoprotein (U1RNP), and Scl/PM antibodies (4.0% vs 16.1%, p < 0.001, 3.5% vs 7.4%, p = 0.041, and 0.0% vs 2.0%, p = 0.042 respectively) and positive for anti-RNA polymerase (RNAP) III antibody (24.9% vs 8.3%, p < 0.001). Here, SNRNP70 is linked to gastric antral vascular ectasia.
