TCGAretriever (version 1.9.1)

get_mutation_data: Retrieve Mutation Data corresponding to a Genetic Profile of Interest.

Description

Retrieve DNA Sequence Variations (Mutations) identified by exome sequencing projects. This function is the workhorse of the TCGAretriever package for mutation data and can be used to fetch data concerning several genes at once. For retrieving non-mutation data, please use the `get_molecular_data()` function. For large queries (more than 500 genes), please use the `fetch_all_tcgadata()` function.

Usage

get_mutation_data(
  case_list_id,
  gprofile_id,
  glist = c("TP53", "E2F1"),
  dryrun = FALSE
)

Value

data Frame inluding one row per mutation

Arguments

case_list_id

String corresponding to the Identifier of a list of cases.

gprofile_id

String corresponding to the Identifier of a genetic Profile of interest.

glist

Vector including one or more gene identifiers (ENTREZID or OFFICIAL_SYMOL). ENTREZID gene identifiers should be passed as numeric.

dryrun

Logical. If TRUE, all other arguments (if any) are ignored and a representative example is returned as output. No Internet connection is required for executing the operation when `dryrun` is TRUE.

Examples

# Set `dryrun = FALSE` (default option) in production!
x <- get_mutation_data(case_list_id = 'blca_tcga_sequenced',
                       gprofile_id = 'blca_tcga_mutations',
                       glist = c('TP53', 'PTEN'), dryrun = TRUE)
utils::head(x[, c(4, 7, 23, 15, 16, 17, 24, 18, 21)])
