Evaluation of genomic cancer data available in cBioPortal (http://www.cbioportal.org/) indicates that NPY is not frequently amplified (1.12%; 5/447 patients) or mutated (1.34%; 6/447 patients) in the tumors of patients with skin cutaneous melanoma (TGCA Research Network) (107, 108). Here, NPY is linked to cutaneous melanoma.
