Get Independent Eqtl

Source: R/get_independent_eqtl.R
get_independent_eqtl.Rd

Retrieve Independent eQTL Data

  • Finds and returns Independent eQTL Data data for the provided list of genes

  • By default, this endpoint fetches data from the latest GTEx version

The retrieved data is split into pages with items_per_page entries per page

GTEx portal API documentation

Usage

get_independent_eqtl(
  gencodeIds,
  tissueSiteDetailIds = NULL,
  datasetId = "gtex_v8",
  page = 0,
  itemsPerPage = 250
)

Arguments

gencodeIds

A character vector of Versioned GENCODE IDs, e.g. c("ENSG00000132693.12", "ENSG00000203782.5").

tissueSiteDetailIds

Character vector of IDs for tissues of interest. Can be GTEx specific IDs (e.g. "Whole_Blood"; use get_tissue_site_detail() to see valid values) or Ontology IDs.

datasetId

String. Unique identifier of a dataset. Usually includes a data source and data release. Options: "gtex_v8", "gtex_snrnaseq_pilot".

page

Integer (default = 0).

itemsPerPage

Integer (default = 250).

Value

A tibble.
