Hi, 

Anyone knows on which version of the human genome the data in the cbioportal is associated? I've downloaded mutations for several genes, but I've no idea whether they refer to hg18, hg19 or hg38, and didn't found any indication neither on the website nor on the forum.

thanks!
Sorry that this isn't explicit on the portal. All variants in all studies use `GRCh37.p13` loci and alleles. The autosomes and sex chromosome sequences are equivalent to `hg19`, but the mitochondrial DNA sequence is newer. [Click here](https://www.biostars.org/p/119295/#119308) for details.

The effect of each variant is mapped to canonical isoforms per gene ([as defined by Uniprot](http://www.uniprot.org/help/canonical_and_isoforms)) in [Gencode 19](https://www.gencodegenes.org/stats/archive.html#a19) using [Ensembl's VEP](http://useast.ensembl.org/info/docs/tools/vep/index.html) with the `vcf2maf` and `maf2maf` wrappers that [live here](https://github.com/mskcc/vcf2maf).
