RNPC3 and cancer: Individually, anti-RNP/Sm (OR 1.70, 95% CI 1.16–2.50, p = 0.007), anti-Ro/La (OR 1.79, 95% CI 1.22–2.64, p = 0.003), anti-Scl-70 (OR 1.60, 95% CI 1.29–1.99, p < 0.001), and anti-DNA (OR 1.97, 95% CI 1.31–2.99, p < 0.001) were each associated with significantly increased odds of cancer.
