Where Can I Find The Basepair Positions Of Chromosome Bands?

Question

[Abdel]

Hi everyone,

If I want to know the position of a chromosome band (for example 16p11.2), where can I find those? Thanks in advance!

In this file:

This is not for the latest assembly, but I don't think it will change a lot. You can also check some other information going to

http://hgdownload.cse.ucsc.edu/goldenPath/

and checking the directories.

Thanks you very much!

Thanks to Paulo Nuin, the hg19 version file can be found here: http://hgdownload.cse.ucsc.edu/goldenPath/hg19/database/cytoBand.txt.gz

And the hg38 version can be found here: https://hgdownload.soe.ucsc.edu/goldenPath/hg38/database/cytoBand.txt.gz

And for convenience, updated links for the others: https://hgdownload.soe.ucsc.edu/goldenPath/hg18/database/cytoBand.txt.gz https://hgdownload.soe.ucsc.edu/goldenPath/hg19/database/cytoBand.txt.gz

Your request implies you're interested in human chromosome bands. Some of these are well defined but others are not - in terms of base pair positions in the Golden Path or reference genome assembly. You can spot check some genes that are near boundaries by their cytogenetic map positions in order to verify that the data from the Golden Path agree.
