Ambroise Wonkam is a Cameroonian medical doctor and professor of medical genetics at Johns Hopkins School of Medicine. His research is in sickle cell disease, the genetics of congenital hearing impairment, and ethics in human genetics. He is the current president of the African Society of Human Genetics.
Ambroise Wonkam was born in Yaoundé, Cameroon. He studied at the Faculty of Medicine and Biomedical Sciences of the University of Yaoundé I, where he received his MD in 1995. [1] [2] In 1997, he went to the University of Geneva to train in cell biology before specializing in medical genetics. [2] He received his doctorate in Medical Sciences in the Department of Morphology on the topic Burden of sickle cell disease and prenatal genetic diagnosis in Cameroon (French: Fardeau de la drépanocytose et diagnostic génétique prénatal au Cameroun ). [3]
Wonkam is a medical practitioner in African and European countries. He joined the University of Cape Town as faculty in 2009, where he studied sickle cell disease and why its severity and mortality varied between individuals. [2] He became professor of medical genetics at the Faculty of Medicine where he was the deputy dean of research and director of the Genetic Medicine of African Populations (GeneMAP) program, which he founded in 2017. [2] [4] He became president of the African Society of Human Genetics in 2019. In 2021, he was named director of genetics at the Johns Hopkins School of Medicine. [4]
Wonkam is spearheading the Three Million African Genomes project, which aims to sequence the DNA of three million Africans in order to make up for systemic shortfalls in the study of the human genetic diversity of Africans. [5] He has proposed that the project be funded by African countries. [6] In 2022, he was a guest editor for special issues of Nature calling for the decolonization and elimination of racism in science. [7]
Genetic counseling is the process of investigating individuals and families affected by or at risk of genetic disorders to help them understand and adapt to the medical, psychological and familial implications of genetic contributions to disease. This field is considered necessary for the implementation of genomic medicine. The process integrates:
Medical genetics is the branch of medicine that involves the diagnosis and management of hereditary disorders. Medical genetics differs from human genetics in that human genetics is a field of scientific research that may or may not apply to medicine, while medical genetics refers to the application of genetics to medical care. For example, research on the causes and inheritance of genetic disorders would be considered within both human genetics and medical genetics, while the diagnosis, management, and counselling people with genetic disorders would be considered part of medical genetics.

James Van Gundia Neel was an American geneticist who played a key role in the development of human genetics as a field of research in the United States. He made important contributions to the emergence of genetic epidemiology and pursued an understanding of the influence of environment on genes. In his early work, he studied sickle-cell disease and acatalasia. conducted research on the effects of radiation on survivors of the Hiroshima atomic bombing.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. The most common type is known as sickle cell anemia. It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. This leads to a rigid, sickle-like shape under certain circumstances. Problems in sickle cell disease typically begin around 5 to 6 months of age. A number of health problems may develop, such as attacks of pain in joints, anemia, swelling in the hands and feet, bacterial infections, dizziness and stroke. Long-term pain may develop as people get older. The average life expectancy in the developed world is 40 to 60 years. It often gets worse with age. All the major organs are affected by sickle cell disease. The liver, heart, kidneys, gallbladder, eyes, bones, and joints also can suffer damage from the abnormal functions of the sickle cells, and their inability to flow through the small blood vessels correctly.
James Edward Bowman Jr. was an American physician and specialist in pathology, hematology, and genetics. He was a professor of pathology and genetics at the Pritzker School of Medicine at the University of Chicago. He published more than ninety works across the fields of human genetics; population genetics; and ethical, legal and public policy issues in human genetics. He received many awards, including the Chicago African American History Makers Award and recognition from the Hastings Center and Stanford’s Kaiser Family Foundation, and Howard University.
For preventing Tay–Sachs disease, three main approaches have been used to prevent or reduce the incidence of Tay–Sachs disease in those who are at high risk:
Karin J. Blakemore is a leading medical geneticist and works in gynecology and obstetrics, human genetics, and maternal and fetal medicine. Dr. Blakemore's major contribution to medicine stems from her research as a member of a team that aimed to fight genetic disorders through the in utero transplantation of donor cells using a mouse as an animal model. Through this initial research in regards to first trimester prenatal diagnosis, Blakemore initiated the beginning of research on in utero bone marrow transplantation for genetic disorders of the fetus.

He is one of the world's foremost experts on sickle-cell disease.
Stuart Holland Orkin is an American physician, stem cell biologist and researcher in pediatric hematology-oncology. He is the David G. Nathan Distinguished Professor of Pediatrics at Harvard Medical School. Orkin's research has focused on the genetic basis of blood disorders. He is a member of the National Academy of Sciences and the Institute of Medicine, and an Investigator of the Howard Hughes Medical Institute.
The He Jiankui affair is a scientific and bioethical controversy concerning the use of genome editing following its first use on humans by Chinese scientist He Jiankui, who edited the genomes of human embryos in 2018. He became widely known on 26 November 2018 after he announced that he had created the first human genetically edited babies. He was listed in Time magazine's 100 most influential people of 2019. The affair led to ethical and legal controversies, resulting in the indictment of He and two of his collaborators, Zhang Renli and Qin Jinzhou. He eventually received widespread international condemnation.

He is an Emeritus Professor in the Departments of Paediatrics and Genetics at the University of Adelaide.
Three Million African Genomes (3MAG) is a human genetics project inaugurated by Ambroise Wonkam of Cape Town University in South Africa. The project's aim is to correct for the systemic shortfall in the collection and analysis of genomic data of Africans, who have the widest genetic variation among human populations, via sequencing to capture "the full scope of variation to improve health care, equity and medical research globally". Three million is the initial rough estimate of the sample size required to capture the variation.

The genetic history of the African diaspora is composed of the overall genetic history of the African diaspora, within regions outside of Africa, such as North America, Central America, the Caribbean, South America, Europe, Asia, and Australia; this includes the genetic histories of African Americans, Afro-Canadians, Afro-Caribbeans, Afro-Latinos, Afro-Europeans, Afro-Asians, and African Australians.
The genetic history of West Africa encompasses the genetic history of the people of West Africa. The Sahara served as a trans-regional passageway and place of dwelling for people in Africa during various humid phases and periods throughout the history of Africa.
