I frequently have a list of long gene names (not symbols) that I need to map to Entrez IDs. For example, instead of having the gene symbol PTEN, I have the long gene name "phosphatase and tensin homolog". I don't see where Biomart supports the mapping of long gene names (using database: Ensembl genes 64, Sanger UK).
I've tried using MatchMiner. However, often the list of long gene names I have uses something other than "official" gene names and MatchMiner has trouble mapping. It's also quite slow.
What other resources are people using to batch map large lists of long gene names? I'd appreciate any tips.
