Figure 3From: Genomic profiling of breast tumours in relation to BRCAabnormalities and phenotypesDifferences in genome architecture patterns were observed between the identified subgroups. Two tumour genomes are shown for each of the four subgroups. (a) The BRCA1- and (b) BRCA2-related subgroups are characterised by relatively long segments of deletions with occasional high-level amplifications. (c) The simple-profile subgroup resembled the BRCA1- and BRCA2-related subgroups but displayed considerably less complex genomes. (d) The GII-high-III subgroup was characterised by small and closely spaced segments of genomic alterations throughout their tumour genomes along with occasional high-level amplifications. GII = genomic instability index.Back to article page
