![I Also Had an Increased Risk for Ulcerative Colitis,
But a SNP that is Also Associated with Colonic CD
I Have a
33% Increased Risk
for Ulcerative Colitis
HLA-DRA (rs2395185)
I Have the Same Level

as Another Male Who Has Had
Ulcerative Colitis for 20 Years
āOur results suggest that at least for the SNPs investigated
[including HLA-DRA],
colonic CD and UC have common genetic basis.ā

The human body is host to 100 trillion microorganisms, ten times the number of DNA-bearing cells in the human body, and these microbes contain 300 times the number of DNA genes that our human DNA does. The microbial component of our "superorganism" is comprised of hundreds of species with immense biodiversity. To put a more personal face on the "patient of the future," I have been collecting massive amounts of data from my own body over the last seven years, which reveals detailed examples of the episodic evolution of this coupled immune-microbial system. An elaborate software pipeline, running on high performance computers, reveals the details of the microbial ecology and its genetic components, in health as well as in disease. Not only can we compare a person with a disease to a healthy population, but we can also follow the dynamics of the diseased patient. We can look forward to revolutionary changes in medical practice over the next decade.
