Validation of autoAb expression by indirect ELISA. Six MMD-specific proteins identified through a fitSNPs approach were analyzed by indirect ELISA for IgG levels against these antigens in MMD sera. All antigens were found to be significantly increased in MMD (n = 46) compared to CVD controls (n = 22): (A) STRA13 (p = 0.01), (B) APP (p = 0.01), (C) CTNNB1 (p = 0.02), and (D) GPS1 (p = 0.01), (E) ROR1 (p = 0.04), and (F) EDIL3 (p = 0.02) (OD@405 nm = optical density at 405 nm) (G) A ROC curve built on a logistic regression model using 6 autoAbs ELISA data (Area Under Curve = 0.76) demonstrates a 74% sensitivity, 77% specificity, 87% PPV, 59% NPV and overall 75% accuracy set of all MMD samples tested.
