The result showed that SERPINH1 had a positive relationship with GBMLGG, LGG, PCPG (pheochromocytoma and paraganglioma), KICH, OV, PAAD (pancreatic adenocarcinoma), LIHC, READ, COAD, COADREAD, BLCA, KIPAN, PRAD, BRCA, THCA (Thyroid carcinoma), KIRC, and KIRP among 60 ICP genes, while it had a negative correlation with TGCT. Here, SERPINH1 is linked to hereditary pheochromocytoma-paraganglioma.
