Get Linkage Disequilibrium Data

Source: R/get_linkage_disequilibrium_data.R
get_linkage_disequilibrium_data.Rd

Find linkage disequilibrium (LD) data for a given gene.

This endpoint returns linkage disequilibrium data for the cis-eQTLs found associated with the provided gene in a specified dataset. Results are queried by gencode ID. By default, the service queries the latest GTEx release. Specify a dataset ID to fetch results from a different dataset.

Usage

get_linkage_disequilibrium_data(
  gencodeId,
  datasetId = "gtex_v8",
