1 Sept 2010
Abstract excerpt
BACKGROUND: African-Americans generally have lower circulating levels of 25 hydroxyvitamin D [25(OH)D] than Whites, attributed to skin pigmentation and dietary habits. Little is known about the genetic determinants of 25(OH)D levels nor whether the degree of African ancestry associates with circulating 25(OH)D. METHODS: With the use of a panel of 276 ancestry informative genetic markers, we estimated African and...
