Sample Name: Afro-Ecuadorian

Sample UID: SA004509S

Sample Description:This sample consists of Afro-Ecuadorian individuals. Samples were collected by the Faculty of Medical Sciences of Central University of Ecuador, and by the Laboratory of Human Genetics, Department of Biology and Biotechnology, LSpallanzani, University of Pavia, Italy. Informed Consent was signed by every sample donor, and all samples were anonymised. The study was approved by the ethical committee of the Capital Region of Denmark (H-1-2011-081) and complies with the ethical principles of the 2000 Helsinki Declaration of the 2006 World Medical Association. Samples were only used for research purposes.
