ensg_to_entrez_id_map_ensembl_feb2014.tsv erroneously assigns Entrez ID

[gjoseph15]

we are using vcf2maf prior to import to our local cBioPortal instance. We encounter a warning from cBioPortal's data validator that the MAF data contains Hugo Symbol:Entrez ID combinations that are incorrect.

Upon deeper inspection, the "ensg_to_entrez_id_map_ensembl_feb2014.tsv" file contains multiple instances where several Entrez ID's trace back to the same ENSG#, but no additional columns exist in the file to successfully pair the Hugo symbol to the specific Entrez from the cluster and so the pipeline incorrectly assigns the values.
