Admixed ancestral composition with Amerindian predominance at the Peruvian Alzheimer Disease Initiative (PeADI)

Current genetic studies for AD and other dementias are making efforts to incorporate underrepresented populations including admixed Latinos. Peruvian population is characterized by admixed ancestry with a significant Amerindian component, which varies according to specific regions across Peru. The Peruvian Alzheimer Disease initiative (PeADI) was developed to ascertain a cohort for AD and other related dementias for genetic studies in Peru. We aim to determine the patterns of continental ancestry by regions across Peru.
