GA4GH (Global Alliance for Genomics and Health) http://genomicsandhealth.org/ talks about building the “Google search for genomic data” using RESTful API.
I found an interesting example here: “A global search engine for genetic mutations.” https://beacon-network.org
The example search suggested on the site is:
13 : 32936732 G > C
I tried another random one from SNPedia:
1 : 155204793 C > T
Notice how the link is formatted: https://beacon-network.org/#/search?chrom=1&pos=155204793&ref=C&allele=T&rs=GRCh37
I imagine that the search URL structure is then passed verbatim to other databases that are registered on the Beacon network.
