Dear list, I have a list of SNPs with chromosome location, and trying to see which ones are non-synonymous. Are there any packages/functions that can distinguish synonymous and non-synonymous SNPs? I tried to search the list, but could not find anything related. Thanks in advance.

Hi Xiwei, do you mean SNPs that result in non-synonymous vs synonymous coding? Then a biomart query might do the job and therefore the package biomaRt could be used to query from within R. There is a filter in biomart for different consequence types of SNPs, one of which is NON_SYNONYMOUS_CODING. You can check which filter seems appropriate This lengthy Url represents a possible query in the biomart web interface: http://www.biomart.org/biomart/martview?VIRTUALSCHEMANAME=default&ATTR IBUTES=hsapiens_snp.default.snp.refsnp_id|hsapiens_snp.default.snp.chr _name|hsapiens_snp.default.snp.chrom_start|hsapiens_snp.default.snp.co nsequence_type_tv|hsapiens_snp.default.snp.ensembl_type|hsapiens_snp.d efault.snp.ensembl_peptide_shift|hsapiens_snp.default.snp.phenotype_de scription|hsapiens_snp.default.snp.phenotype_name&FILTERS=hsapiens_snp .default.filters.consequence_type."NON_SYNONYMOUS_CODING"&VISIBLEPANEL =resultspanel it should be possible to set identical parameters in the bioconductor package biomaRt although I didn't try this yet.

Michael, Thanks a lot for your help. I will give it a try. Is it good for novel SNPs not in the dbSNP? The SNPs I got are from a sequencing project, many of them are not in dbSNP.

I'm not sure BioC is the tool you want to use. Have you tried something like BioPerl: http://www.bioperl.org/Core/Latest/bioscripts.html#scripts_utilities_p airwise_kaks_pls "Takes DNA sequences as input, aligns them as proteins, projects the alignment back into DNA and estimates the Ka (non-synonymous) and Ks (synonymous) substitutions." ________________________________________ From: bioconductor-bounces@stat.math.ethz.ch [bioconductor- bounces@stat.math.ethz.ch] On Behalf Of Wu, Xiwei [XWu@coh.org] Sent: 29 January 2010 17:26 To: Michael Dondrup Cc: bioconductor at stat.math.ethz.ch Subject: Re: [BioC] Distinguish Synonymous vs. Non-synonymous SNPs Michael, Thanks a lot for your help.

Dear all, I found that the findOverlaps function does not work properly if the space levels do not match exactly between subject and query. Has anyone noticed the same problem? I am using the R-2.10.0 and IRanges-1.4.0. Is this problem being fixed in the developmental version? Thanks.

It seems to me that it is working correctly but you can't assume that the order of ranges at time of construction serves as the order in the ultimate object. A lexicographic ordering by space names is used. Challenging to interpret but if you look at the values of a and b before interpreting your findOverlaps result it starts to make sense. > a <- RangedData(IRanges(start=rep(1,7), end=rep(10,7)), space=paste("chr", c(2, 10, 9, 5, 6, 3, 7), sep="")) > a RangedData with 7 rows and 0 value columns across 7 spaces space ranges | <character> <iranges> | 1 chr10 [1, 10] | 2 chr2 [1, 10] | 3 chr3 [1, 10] | 4 chr5 [1, 10] | 5 chr6 [1, 10] | 6 chr7 [1, 10] | 7 chr9 [1, 10] | > b <- RangedData(IRanges(start=rep(1,7), end=rep(10,7)), space=paste("chr", c(2, 10, 18, 5, 21, 3 , "X"), sep="")) > b RangedData with 7 rows and 0 value columns across 7 spaces space ranges | <character> <iranges> | 1 chr10 [1, 10] | 2 chr18 [1, 10] | 3 chr2 [1, 10] | 4 chr21 [1, 10] | 5 chr3 [1, 10] | 6 chr5 [1, 10] | 7 chrX [1, 10] | > findOverlaps(a,b) RangesMatchingList of length 7 names(7): chr10 chr2 chr3 chr5 chr6 chr7 chr9 > as.matrix(.Last.value) query subject [1,] 1 1 [2,] 2 3 [3,] 3 5 [4,] 4 6 On Sat, Jan 30, 2010 at 1:09 PM, Wu, Xiwei <xwu at="" coh.org=""> wrote: > Michael, > > Here is one example.
