Remove Version Numbers in Raw GTEx (GENCODE) Gene IDs
Description
Remove the '.version' part in raw GTEx (GENCODE) gene IDs to produce Ensembl IDs.
Usage
cleanid(gtex_id)
Arguments
gtex_id |
Character vector of GTEx (GENCODE) gene IDs |
Value
Character vector of Ensembl IDs
Examples
gtex_id <- c("ENSG00000227232.4", "ENSG00000223972.4", "ENSG00000268020.2")
cleanid(gtex_id)
Gene ID Mapping for Genotype-Tissue Expression (GTEx) Data
Description
Map Ensembl IDs to Entrez Gene ID, HGNC symbol, and UniProt ID, with basic annotation information such as gene type.
Usage
grex(ensembl_id)
Arguments
ensembl_id |
Character vector of Ensembl IDs |
Value
This function returns a data frame with the same number of rows as the length of input Ensembl IDs, containing:
-
ensembl_id- Input Ensembl ID -
entrez_id- Entrez Gene ID -
hgnc_symbol- HGNC gene symbol -
hgnc_name- HGNC gene name -
cyto_loc- Cytogenetic location -
uniprot_id- UniProt ID -
gene_biotype- Gene type
The elements that cannot be mapped will be NA.
Examples
# Ensembl IDs in GTEx v6p gene count data
data("gtexv6p")
# select 100 IDs as example
id <- gtexv6p[101:200]
df <- grex(id)
# Rows that have a mapped Entrez ID
df[
!is.na(df$"entrez_id"),
c("ensembl_id", "entrez_id", "gene_biotype")
]
