Getting Genetics Data From NIH
The web page https://ghr.nlm.nih.gov/about/data-files-api describes how to get certain types of genetics data from the National Institutes of Health (NIH).
In particular:
Information from individual condition, gene, chromosome, and mtDNA pages is available in JSON and XML.
Add ?report=json or ?report=xml to the page's URL, e.g., https://ghr.nlm.nih.gov/condition/alzheimer-disease?report=json
To get JSONP that passes the data to a function of your choice, also add &p=somefunction
A compendium of all those XML instances is available in one XML file: https://ghr.nlm.nih.gov/download/ghr-summaries.xml
