Hi Is there a way to convert non-HUGO gene symbol identifiers to entrez gene or other ids? Example: ACSL1 aka ACS1; LACS; FACL1; FACL2; LACS1; LACS2; ACSL1 Thanks in advance -burak [[alternative HTML version deleted]]

Hi Burak, You can always use the ALIAS2EG and the SYMBOL mappings in the organism annotation packages. So for example using the human package org.Hs.eg.db: library(org.Hs.eg.db) IDs = c("ACS1","LACS","FACL1","FACL2","LACS1","LACS2","ACSL1") #1st use ALIAS2EG to get entrez gene IDs for these EGs = mget(IDs, org.Hs.egALIAS2EG, ifnotfound=NA) #have a look at these: EGs #At this point you can already see that these all map to the same gene ID #BUT, you can get the most popular symbol by using the SYMBOL mapping: mget(as.character(EGs[1]),org.Hs.egSYMBOL, ifnotfound=NA) Hope this helps, Marc burak kutlu wrote: > Hi > Is there a way to convert non-HUGO gene symbol identifiers to entrez gene or other ids? > Example: > ACSL1 aka ACS1; LACS; FACL1; FACL2; LACS1; LACS2; ACSL1 > Thanks in advance > -burak > > > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor > >
