Researchers led by Hakon Hakonarson at The Children's Hospital of Philadelphia used a genome-wide association study to follow up on a SNP previously linked to obeisty in Caucasians. In their study, published today in PLoS ONE, they looked at common variants among both Caucasian and African American children and found one SNP common to both and one common only to African Americans. The second SNP, they write, might capture the "ancestral origin" of the variation.
