Dear list, Now I am working on Affy Human Exon 1.0 array, when I search probeset 2483547 using probeset.to.gene("2483547") in xmapcore package, it give null. But in affy annotation file and websites, both of them given the annotation about this probeset is gene EIF3F on chr2. But this gene EIF3F is on chr11. How can I get the correctly annotation? Thank you very much in advance.

Dear Fabrice, This probeset happens to match 3 location in the genome (variants/paralogs of EIF3F on chr2, 11, 21), see http://xmap.picr.man.ac.uk/ The good thing is that it does in a uniform way for all 4 probes - so most likely matches a specific domain for 3 variants of EIF3F gene. Which variant is most pronounced in your case you can check with other probesets, eg: 3925009.
