We've been using the xenabrowser's old mapping file; we should be using the latest biomaRt annotated hugo symbols, taking into account the potential aliases while maintaining roughly the correct gene coordinates (for example, a gene symbol might be a legacy name for two different genes in two different chromosomes - the gene shouldn't jump between chromosomes, and roughly stay the same coordinates even after hg19 -> hg38 and other adjustments).
