Compilation of TCGA molecular subtypes
TCGAbiolinks retrieved molecular subtypes information from TCGA samples. The functions PanCancerAtlas_subtypes and TCGAquery_subtype can be used to get the information tables.
While the PanCancerAtlas_subtypes function gives access to a curated table retrieved from synapse (probably with the most updated molecular subtypes) the TCGAquery_subtype function has the complete table also with sample information retrieved from the TCGA marker papers.
PanCancerAtlas_subtypes: Curated molecular subtypes.
Data and description retrieved from synapse (https://www.synapse.org/#!Synapse:syn8402849)
Synapse has published a single file with all available molecular subtypes that have been described by TCGA (all tumor types and all molecular platforms), which can be accessed using the PanCancerAtlas_subtypes function as below:
subtypes <- PanCancerAtlas_subtypes()
DT::datatable(
data = subtypes,
filter = 'top',
options = list(scrollX = TRUE, keys = TRUE, pageLength = 5),
rownames = FALSE
)The columns “Subtype_Selected” was selected as most prominent subtype classification (from the other columns)

TCGAquery_subtype: Working with molecular subtypes data.

These subtypes will be automatically added in the summarizedExperiment object through GDCprepare. But you can also use the TCGAquery_subtype function to retrieve this information.
