In total, we identified 25, 32, 76, and 40 protein spots recognized by sera IgGs from normal controls (Fig. 4B.a,e,i), chagasic patients characterized as clinically asymptomatic (CD0–CD1) (Fig. 4B.b,f,j) and symptomatic (CD2–CD3) (Fig. 4B.c,g,k), and non-chagasic/other cardiomyopathy (OCM) patients (Fig. 4B.d,h,l). The gene discussed is CD2; the disease is Hematuria.
