Map Gene Symbols to biotype & description via biomaRt (GRCh38 -> GRCh37 fallback)

map_gene_class_using_biomarRt.Rd

First connect to Ensembl GRCh38 (www.ensembl.org) to query gene_biotype and description in batch; for unmapped genes, automatically fallback to GRCh37 (grch37.ensembl.org). Finally append three columns for each gene:

  • biotype

  • description

  • infer_version – "GRCh38" / "GRCh37" / "unmapped"

Usage

map_gene_class_using_biomarRt(genes, gene_col = "Gene", quiet = FALSE)

Arguments

genes

Character vector of gene symbols, or data frame/tibble containing gene symbols

gene_col

Column name (when genes is a table), default "Gene"

quiet

Logical; if TRUE, suppress progress messages

Value

Data frame with same structure as input, plus biotype, description, infer_version

Examples

if (FALSE) { # \dontrun{
map_gene_class_using_biomarRt(c("TP53", "IGHV1-69", "TRAC", "MIR21"))

df <- tibble::tibble(Gene = c("TP53","XIST","SNORD14A"))
map_gene_class_using_biomarRt(df, gene_col = "Gene")
} # }
