Hi David,

you can use the UCSC website. in addition to the genome browser which is fine to look at many points, you'll have a table browser where you'll be able to access data of what you're searching for.

Hi David,

A tag-SNP is a SNP that represent the LD pattern of a region. Therefore, without this information (Ld), it is not possible to select tag-SNPs. You can use the LDLink web-page (from NIH) to check the LD pattern around your candidate regions or between your candidate SNPs. You can use the LDHap option to check the LD between markers using only the rs. However, I guess that there is no option to extract tag-SNPs from the results. You will have to do it manually or to extract the LD results and to apply in another software that performs the selction of the tag-SNP. Additionally, you can also select your SNPs based on the functional evidence.

UCSC has tag SNP option tracks for its genome browser and of course you can access these information from the table browser to get the related files. tag SNP have been selected among databases needed by genome and population studies.

Thank you very much Frederic Lepretre and Pablo Fonseca for answering my question. I did not know that you could see tag SNPs on UCSC website. So, I will check it. Regarding LDlink web tools looks very interesting and easy way to found several types of genetics data.
