Researchers at RPCI, Duke Develop Method
to Pinpoint Factors That Cause Disease
BUFFALO — With the ability to sequence human genes comes an onslaught of raw material about the genetic characteristics that distinguish us, and wading through these reserves of data poses a major challenge for life scientists. Researchers at Roswell Park Cancer Institute (RPCI) and the Center for Human Genome Variation at Duke University Medical Center (DUMC) have developed an approach for analyzing data that can help researchers studying genetic factors in disease to quickly cull out relevant genetic patterns and identify variants that lead to particular disorders. The researchers outline this new approach in a study published in the September issue of The American Journal of Human Genetics. They note that while genome-wide association studies (GWASs), which analyze the DNA of many people in order to reveal genetic variations associated with disease, have reported thousands of variants associated with different traits, it’s very difficult to isolate “causal variants,” those genetic i...
