Dear Genome Browser team,

 

I was looking for a variant at the splice donor of PMS2 (chr7:6017218, G>T [cDNA], C>A [genomic]), and noticed on the UCSC genome browser that, while there was a entry in the ClinVar track, there is no corresponding entry in the dbSNP (147) track (see screenshot 1). I then clicked the ClinVar entry (screenshot 2), and found the dbSNP entry (876661113), which I could click to access it. I was just surprised to not see it in the all SNPs (147) and Flagged SNPs (147) tracks, and was wondering if it is not displaying properly on my end.

 

I also tried to access the ClinVar variation report from screenshot 2. It redirected me to this URL (http://www.ncbi.nlm.nih.gov/clinvar/variation/231656/), which is a different variant (screenshot 3). However, if I click on the ClinVar Allele submission links, they link to the correct submission, which then allowed me to go to the correct ClinVar page (http://www.ncbi.nlm.nih.gov/clinvar/variation/234604) (screenshot 4). I’m wondering if there’s something on my end that’s causing this error.

 

Please let me know if there are any questions or confusion, or if you cannot replicate my issue.

Thanks for all your help.

 

Cheers,

Oliver

Dear Genome Browser team,

 

I forgot to clarify that I’m using the hg19/GRCh37 build of the human genome.

Thanks.


Cheers,

Oliver

Hello Oliver,

Thank you for your email. rs876661113 is a brand new SNP that was not included in the database dump files for the initial release of b147, which explains why there is no entry in our SNP147 track.

As for the ClinVar links, you uncovered a bug - thank you for bringing it to our attention.

If you have any further questions, please reply to gen...@soe.ucsc.edu. All messages sent to that address are archived on a publicly-accessible forum. If your question includes sensitive data, you may send it instead to genom...@soe.ucsc.edu.

Regards,
Luvina
