The TGen team performed deep genomic profiling,
integrating gene copy number, gene expression and DNA methylation datasets on a collection of 35 breast - brain metastases samples.
The team
integrated three, complementary
gene sequencing approaches to look for mutations in tumor cells from SS patients: whole - genome sequencing in six subjects, sequencing of all protein - coding regions (exomes) in 66 subjects, and comparing variation in the
number of
copies of all
genes across the genome in 80 subjects.
The authors next took 997 tumors in the discovery set,
integrated copy number and
gene expression data, and performed clustering analyses to identify subgroups of tumors with distinct features and clinical outcomes.
However, being a complex multistep process, cancer cytogenetics are broadened to «cytogenomics,» with complementary resources on: general databases (nucleic acid and protein sequences databases; cartography browsers: GenBank, RefSeq, UCSC, Ensembl, UniProtKB, and Entrez
Gene), cancer genomic portals associated with recent international
integrated programs, such as TCGA or ICGC, other fusion
genes databases, array CGH databases,
copy number variation databases, and mutation databases.
