Which chromosome a gene belongs to, in human?

Question

[Marouen Ben Guebila]

Hi all,

I have a list of human genes (ENTREZ gene ID).

I would like to know the location of each gene.

i.e. : gene 8639 -> Chromsome 17.

I use R.

Cheers

Using Org.Hs.eg.db :

> unlist(mget(x = '8639',envir = org.Hs.egCHR,ifnotfound = NA))
8639
"17"

> unlist(mget(x = '8639',envir = org.Hs.egCHRLOC,ifnotfound = NA))
 8639.17
41003201

Biomart is your friend. That URL goes to a search for the chromosome of the gene with Entrez ID 8639. Just add more genes in the "Filter" section or use the R or perl interface if that's more convenient.
