The genomics of ethnicity

Researchers have assembled the first-ever map of copy number variants (CNV)-- duplications, deletions or rearrangements in the genome that result in different gene copy numbers -- in African Americans. The study, appearing in linkurl:__BMC Genetics__;http://www.biomedcentral.com/bmcgenet/ today, also identified two CNVs that differed in frequency between African American genomes and those in people of European descent. linkurl:Joseph McElroy,;http://www.msgenes.ucsf.edu/fellows_Joseph_McElroy_P

"The reason we wanted to [compare CNVs in African Americans and whites] is because most of the literature on this has been done in whites," he said. "On a genome-wide level, African Americans haven't been studied for diseases that are present in African American populations." McElroy and his colleagues screened the...
