Douglas C. Wallace, PhD, a pioneering genetics researcher who founded the field of mitochondrial genetics in humans, will receive the 2012 Genetics Prize of The Gruber Foundation. Wallace is being honored with this prestigious international award for his groundbreaking achievements in helping science understand the role of mitochondriathe "power plants" of cellsin the development of disease and as markers for human evolution.
He will receive the award November 9 in San Francisco at the Annual Meeting of the American Society of Human Genetics, where he will also deliver a lecture titled "A Bioenergetic Perspective on Origins, Health, and Disease".
"Douglas Wallace's contributions to our understanding of mitochondrial genetics have changed the way human and medical geneticists think about the role of mitochondria in human health and disease," said Elizabeth Blackburn, chair of the Selection Advisory Board to the Prize. Blackburn is the 2006 Gruber Genetics Prize laureate and shared the 2009 Nobel Prize in Physiology and Medicine.
Wallace began his research on mitochondrial biology 40 years ago, at a time when few people thought the study of mitochondria and its DNA (mtDNA) would have any significant applications for clinical medicine. In the early 1970s, Wallace and associates demonstrated that the mtDNA coded for heritable traits by developing the cybrid transfer technique and showing that chloramphenicol resistance was cytoplasmically inherited. This system permitted them to delineate the characteristics of cytoplasmic genetics. Then in the late 1970s, Wallace demonstrated that the human mtDNA is inherited solely through the mother. Using maternal inheritance as a guide, Wallace identified the first inherited mtDNA disease, Leber's hereditary optic neuropathy (LHON), and subsequently linked mtDNA mutations to a wide range of clinical symptoms, including deafness, neuropsychiatric disorders, cardiac and muscle problems, and metabolic diseases such as diabetes. Wallace also showed that mtDNA mutations accumulate in human tissue with age, and thus may play a role in age-related diseases, such as heart disease and cancer. In addition, he found that the levels of these age-related mtDNA mutations are higher in the brains of people with certain neurodegenerative diseases, including Alzheimer disease, Parkinson disease and Huntington disease.
Wallace's research has also made a major contribution to the field of molecular anthropology. Using mtDNA variation, he has reconstructed the origins and ancient migrations of women, tracing all mtDNA lineages back some 200,000 years to a single African originthe so-called mitochondrial Eve.
"The impact of Doug Wallace's visionary research has been remarkable," said Huda Zoghbi, a member of Selection Advisory Board and the 2011 laureate of the Gruber Neuroscience Prize. "His discovery of the first mtDNA mutations in humans opened up the field of mitochondrial genetics and demonstrated the role of mitochondria in many human diseases. It's an extraordinary legacyand he is richly deserving of this award."
