For melanoma cell lines, the same lack of correlation between gene amplification and CDKN2A mutational status was observed (see Tables 1 and 2): 14/19 (74%) CDKN2A-mutated and 10/13 (77%) CDKN2A-wild-type cell lines were found to carry amplification in at least one gene locus. Here, CDKN2A is linked to melanoma.
