Searching glycoproteins with a MW of about 50 kD in Table 2 found that alpha-1-B-glycoprotein (51.9 kD) and alpha1 antitrypsin (45.7 kD) were also related to carcinoma diagnosis [49,50,51,52], which could be further studied for PC diagnosis. This evidence concerns the gene SERPINA1 and pachyonychia congenita.
