A nationwide team of researchers, funded in part by the National Human Genome Research Institute (NHGRI), one of the National Institutes of Health (NIH), has produced the first sequence-based map of large-scale structural variation across the human genome.
Recently created maps such as the HapMap have catalogued the patterns of small-scale variations in the genome that involve single DNA letters, or bases.  A sequence-based map provides much finer resolution and location information.
Researchers constructed the structural variation map by partially sequencing the genomes of eight people: four people of African descent, two of Asian descent and two of European descent. Sequence data …read more
