# Authoritative source on human cytogenetic regions?

I am looking for a database that would keep track of human cytogenetic regions and genomic coordinates per genome assembly. I had expected the Genome Reference Consortium to have it, or Ensembl, or NCBI, but I could not find it.

Is there a place with a translation table between human cytogenetic regions and genomic coordinates?

## EDIT

After benn's answer I found that you can also get this information from Ensembl's REST API: https://rest.ensembl.org/info/assembly/homo_sapiens?content-type=application/json&bands=1.

I have transformed the data provided by Ensembl and generated a CSV file with the cytogenetic regions:

• Do you look for a database a paper with a table or what? To which genome should these genomic coordinates be from?

hgdownload.cse.ucsc.edu/goldenPath/hg38/database/cytoBand.txt.gz

• Hey thanks!, do you know why is there in hgdownload.cse.ucsc.edu/goldenPath/hg38/database/ also the file cytoBandIdeo.txt.gz? I checked, and it has exactly the same info as cytoBand.txt.gz. BTW: do you know what the fourth column in cytoBand.txt.gz means? It has values like: gneg, gpos25, gpos50, gpos100, acen, etc.. Apr 25 '19 at 16:01
