MyGene.info moved to GRCh38/hg38 for human genes with hg19 still supported

GRCh38 (or hg38) is the latest human genome assembly, which was released almost a year ago. MyGene.info is now moved to support GRCh38 by default for human genes, but the data (including queries) based on previous assembly version (GRCh37/hg19) are still supported. Here are some details about this change:

  • genomic_pos field is now based on hg38

    This field contains the genomic location of the given gene, the start/end positions are now based on hg38:

In [1]: mg.getgene('1017', fields='genomic_pos')  
Out[1]:  
{'_id': '1017',
 'genomic_pos': {'chr': '12',
  'end': 55972784,
  'start': 55966769,
  'strand': 1},
}
  • exons field is now based on hg38

    This field contains the genomic locations of exons, as well as cdsstart/cdsend, txstart/txend data. All these values are now based on hg38:
