In the iCCA vs. CIR comparison, seven proteins showed higher abundance in the iCCA patient group, among which haptoglobin (HP), cAMP-dependent protein kinase catalytic subunit beta (PRKACB), heat shock protein (HSP) 90-alpha A2 (HSP90AA2P) were previously reported with respect to liver cancer. Here, PRRT2 is linked to infantile convulsions and choreoathetosis.
