Diabetes Risk and Genetics: Keep Getting Those Checkups and Watch Your Weight

Recent genetic discoveries have taught researchers a lot about type 2 diabetes, and identified particular genetic variants that can influence a person's risk of developing the condition. But two studies published this week in the New England Journal of Medicine conclude that genetic information still pales ...

My Mind Has Been Blown By Genome Sequencing

When I was 12 years old I did my first Punnett square and decided that genetics was absolutely, most definitely the coolest thing ever. When I was 13 years old they started the Human Genome Project. The task of sequencing all three billion base pairs in a person’s genome was the most enormous project I ...

ASHG Speakers: People Want Their Genetic Data

The pace of human genetic research shows no signs of slowing. SNP chip technology is allowing researchers to make connections between DNA and disease in ways that were never before possible. Fast, cheap whole genome sequencing, and the avalanche of data it will bring, is just around the corner. And for the ...
