Genetic Risk Factor for Coeliac Disease Identified.

...led with technological advances have enabled us to scan variation across the human genome in large numbers of people for association to disease. The Sanger Institute made available to the study the genome data on 1500 British individuals used as controls (i.e without coeliac disease). The consortium stu...

Largest Ever Study of Genetics Behind Common Diseases Published

This approach will undoubtedly herald major advances in how we understand and tackle disease in the future," he adds. Further analysis as part of the Con...

GAB2-A New Alzheimers Gene Identified

...seven organizations contributed to the genome-wide scan using Affymetrix microarray technology. The team screened the DNA from 1,400 individuals who had been clinically assessed with Alzheimers prior death, and simultaneously examined more than 500,000 SNPs or genetic variations to characterize and confir...
