Mutational Signatures (v3.3 - June 2022)
Copy Number Variations (CN) Signatures
Copy number signatures are defined using the 48-channel copy number classification scheme. The scheme incorporates loss-of-heterozygosity status, total copy number state, and segment length to categorise segments from allele-specific copy number profiles (as major copy number and minor copy number respectively i.e. non-phased profiles), and the signatures displayed here were identified from 9,873 tumour copy number profiles obtained from The Cancer Genome Atlas (TCGA) SNP6 array data spanning 33 cancer types.
