Integrated Annotation Services for "BioThings"

From MyGene.info and MyVariant.info towards BioThings API

Annotations centered around bio-entities

Gene

GVariant

V

Pathway

P

D

Metabolite

M

Disease

So many variant annotation resources

dbNSFP

The Exome Aggregation

Consortium (ExAC)

BioGPS.org – a gene portal for biologists

Schematic view of MyVariant.info architecture

Each data source is updated individually. Colors indicate their different updating schedules.

High-performance web service APIs

Schematic view of MyVariant.info architecture

MyVariant.info for the end users:

http://MyVariant.info(currently v1 API, two endpoints)

http://MyVariant.info/v1/query?q=<query>

any query term(s)

matching variant hits

http://MyVariant.info/v1/variant/<variantid>

hgvs id(s)

matching variant object(s)

Both supports batch-mode via POST

Simple API. No sign-up. No API key.
