Hi, Has anyone ever had a case where a SNP was not found in SNPlocs.Hsapiens.dbSNP. 20120608, but is found in dbSNP 137?

Hi Christina, According to the official announcement: http://www.ncbi.nlm.nih.gov/mailman/pipermail/dbsnp- announce/2012q2/000122.html there are 53,558,214 rs ids in dbSNP 137 for Human. But in SNPlocs.Hsapiens.dbSNP.20120608: > library(SNPlocs.Hsapiens.dbSNP.20120608) > sum(getSNPcount()) [1] 45416711 As explained in ?SNPlocs.Hsapiens.dbSNP.20120608, the package (like all other SNPlocs packages) was curated: SNPs from dbSNP were filtered to keep only those satisfying the 3 following criteria: ? The SNP is a single-base substitution i.e. its type is "snp". Other types used by dbSNP are: "in-del", "mixed", "microsatellite", "named-locus", "multinucleotide-polymorphism", etc... All those SNPs were dropped. ? The SNP is marked as notwithdrawn. ? A *single* location on the reference genome (GRCh37.p5) is reported for the SNP, and this location is on chromosomes 1-22, X, Y, MT. In the case of rs7775397, it was dropped because of this last reason. More precisely, the record in ds_flat_ch6.flat for this SNP contains the following CTG lines: CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=32261252 | NT_007592.15 | ctg-start=32201252 | ctg-end=32201252 | loctype=2 | orient=+ CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=? | NT_113891.2 | ctg-start=3732030 | ctg-end=3732030 | loctype=2 | orient=+ CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=? | NT_167245.1 | ctg-start=3540499 | ctg-end=3540499 | loctype=2 | orient=+ CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=? | NT_167246.1 | ctg-start=3604088 | ctg-end=3604088 | loctype=2 | orient=+ CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=? | NT_167248.1 | ctg-start=3522471 | ctg-end=3522471 | loctype=2 | orient=+ CTG | assembly=GRCh37.p5 | chr=6 | chr-pos=? | NT_167249.1 | ctg-start=3609047 | ctg-end=3609047 | loctype=2 | orient=+ That is, more than 1 CTG line corresponding to the reference assembly (GRCh37.p5). This is the reason why the SNP was dropped. I realize now that maybe I could keep those SNPs that have more than 1 CTG line corresponding to the reference assembly as long as exactly 1 of them actually provides a value for the chr-pos field. Would that be reasonable? Thanks, H.

Thanks for your help Tim and Herve. It would be very useful to include the SNPs that have a value for the chr-pos field even if they have more than 1 CTG line for my purposes since I deal with a lot of immune-related genes that tend to be difficult to map. Would it be possible to include these types of SNPs, but flag them as having more than 1 CTG line?

Hi Christina, On 01/16/2013 10:15 AM, Christina Chaivorapol wrote: > Thanks for your help Tim and Herve. > > It would be very useful to include the SNPs that have a value for the > chr-pos field even if they have more than 1 CTG line for my purposes > since I deal with a lot of immune-related genes that tend to be > difficult to map. Would it be possible to include these types of SNPs, > but flag them as having more than 1 CTG line? So I've included them in version 0.99.9 of SNPlocs.Hsapiens.dbSNP.20120608. They're not flagged though. Note that there still is a *single* location on the reference genome that is reported for those SNPs,, because the other "locations" are reported as ? (question mark) and it seems fair to not consider ? as a location. With this new version of the package: > library(SNPlocs.Hsapiens.dbSNP.20120608) > sum(getSNPcount()) [1] 45697775 that is, 281064 more SNPs (i.e. 0.6%) compared to the previous version (i.e. 0.99.8). rs7775397 is one of them now: > rsidsToGRanges("rs7775397") GRanges with 1 range and 2 metadata columns: seqnames ranges strand | RefSNP_id alleles_as_ambig <rle> <iranges> <rle> | <character> <character> [1] ch6 [32261252, 32261252] + | 7775397 K --- seqlengths: ch1 ch2 ch3 ch4 ... chX chY chMT 249250621 243199373 198022430 191154276 ... 155270560 59373566 16569 SNPlocs.Hsapiens.dbSNP.20120608 version 0.99.9 will be available in Bioc devel (requires devel version of R i.e. R 3.0) thru biocLite() in about 45 min. Only the source package for now, which you should be able to install on Windows or Mac with biocLite( , type="source"). Let me know if you have questions about this.
