The Genetics of Humanness

Ajit Varki is Distinguished Professor of Medicine and Cellular & Molecular Medicine, Founding Co-Director of CARTA, Founding Director of the Glycobiology Research and Training Center (GRTC) at UC San Diego, and Adjunct Professor at the Salk Institute. He received basic training in physiology, medicine, biology, and biochemistry at the Christian Medical College, Vellore, The University of Nebraska, and Washington University in St. Louis. He also has formal training and board certification in internal medicine, hematology, and oncology. Dr. Varki is Executive Editor of Essentials of Glycobiology (Cold Spring Harbor Press) and is recipient of a MERIT award from the NIH, and an American Cancer Society Faculty Research Award. Honorific elections include the American Academy of Arts and Sciences, the National Academy of Medicine, the American Society for Clinical Investigation, and the Association of American Physicians. He is also recipient of the three highest honors in his field, the Karl Meyer Award of the Society for Glycobiology, the International Glycoconjugate Organization Award and the Rosalind Kornfeld Award for Lifetime Achievement in Glycobiology. He is recognized for creating the first major open access research journal (J. Clin. Invest., 1996) as well as the first major open access textbook (Essentials of Glycobiology, 2009). He was honored with the Old Cottonian of Eminence Award at the 150th Anniversary of Bishop Cotton Boys School, Bangalore, India, (2015) as well as a Distinguished Faculty Medal and Oration at his medical school alma mater, CMC, Vellore. Significant past appointments include: co-head, UC San Diego Division of Hematology-Oncology; President of the Society for Glycobiology; Editor-in-chief of the Journal of Clinical Investigation; Interim director of the UC San Diego Cancer Center, President of the American Society for Clinical Investigation, and UC San Diego Associate Dean for Physician-Scientist Training. Dr. Varki's research interests are focused on a family of cell surface sugars called sialic acids, and their roles in biology, evolution and disease. Currently active projects are relevant to the roles of sialic acids in microbial infectivity, the regulation of the immune response, the progression and spread of tumors, aging, and unique aspects of human evolution. His group is particularly intrigued to find multiple interrelated differences in sialic acid biology between humans and our closest evolutionary cousins, the "great apes". These differences are a signature of the events that occurred during the last few million years of human evolution, and appear to be relevant to understanding several aspects of the current human condition, both in health and disease. Dr. Varki’s book, Denial (Twelve, Hachette Books 2013), explores a novel "Mind Over Reality Transition (MORT) theory that denying reality and personal mortality was a key step in allowing the emergence of a full theory of mind, and in the origin of our species.

Elaine Mardis is Associate Professor of Genetics, Department of Genetics, Washington University in St. Louis. MO, and Senior Research Scientist, Genetic Systems Division, Bio-Rad Laboratories, Hercules, CA. My research interests predominate in DNA sequencing-related technologies. As Co-Director of the Genome Sequencing Center, I help to select genomes of interest and evaluate the optimal sequencing strategy to apply to each genome. As Director of Technology Development at the GSC, I supervise a group that includes engineers and molecular biologists toward exploring and optimizing the most current technologies related to DNA sequencing, both from the standpoint of commercially available kits and instrumentation to the development of custom devices. This group has been responsible for providing many of the advances that have enabled Genome Sequencing Center production sequencing efforts to progress to higher and higher levels of throughput, efficiency and cost-savings over the years, and those efforts continue. In addition, we now are embarking on projects that center around re-sequencing, or mutational profiling, of many human genomes, namely in the context of trying to understand disease-specific somatic mutations that may predict disease onset or outcomes. This new frontier for genome sequencing of the human will continue to fuel medical discoveries for many years to come.  I also have an active interest in the use of microarray technology, not only for gene expression profiling on spotted arrays using long oligonucleotide probes, but also for exploring large-scale amplification and deletion of segments of the human genome using BAC tile path arrays. These array CGH assays will provide an important adjunct to the information gained from mutational profiling of human patient samples, in helping to understand large-scale phenomena in the course of diseases, especially cancer.

Evan Eichler, PhD, is a Professor and Howard Hughes Medical Institute Investigator in the Department of Genome Sciences, University of Washington School of Medicine, and serves on the CARTA External Advisory Board. He graduated with a B.Sc. Honours degree in Biology from the University of Saskatchewan, Canada, in 1990. He received his PhD in 1995 from the Department of Molecular and Human Genetics at Baylor College of Medicine, Houston, Texas. After a Hollaender postdoctoral fellowship at Lawrence Livermore National Laboratory, he joined the faculty of Case Western Reserve University in 1997 and later the University of Washington in 2004. He was a March of Dimes Basil O’Connor Scholar (1998–2001), appointed as an HHMI Investigator (2005), awarded an AAAS Fellowship (2006) and the American Society of Human Genetics Curt Stern Award (2008), and elected to the National Academy of Sciences (2012) and the National Academy of Medicine (2017). He is an editor of Genome Research and has served on various scientific advisory boards for both the NIH and NSF. His research group provided the first genome-wide view of segmental duplications within human and other primate genomes and he is a leader in an effort to identify and sequence normal and disease-causing structural variation in the human genome. The long-term goal of his research is to understand the evolution and mechanisms of recent gene duplication and its relationship to copy number variation and human disease with a specific emphasis on the genetic architecture of autism and neurodevelopmental delay.

Pascal Gagneux is a Professor of Pathology and Anthropology at UC San Diego and serves as CARTA's Executive Co-Director. He is interested in the evolutionary mechanisms responsible for generating and maintaining primate molecular diversity. The Gagneux laboratory studies cell-surface molecules in closely related primates species. His focus is on glycans, the oligosaccharides attached to glycolipids and glycoproteins of the surfaces of every cell and also secreted into the extra-cellular matrix. His laboratory is exploring the roles of molecular diversity in protecting populations from pathogens as well as potential consequences for reproductive compatibility. Dr. Gagneux’s interest is in how glycan evolution is shaped by constraints from endogenous biochemistry and exogenous, pathogen-mediated natural selection, but could also have consequences for sexual selection. Dr. Gagneux has studied the behavioral ecology of wild chimpanzees in the Taï Forest, Ivory Coast, population genetics of West African chimpanzees, and differences in sialic acid biology between humans and great apes with special consideration of their differing pathogen regimes.

In 2011, while Associate Director of CARTA, Dr. Gagneux helped to establish a graduate specialization in Anthropogeny at UC San Diego. This wholly unique graduate specialization is offered through eight participating graduate programs in the social and natural sciences at UC San Diego.

Yoav Gilad is an associate professor of human genetics at the University of Chicago. His research is focused on studying genetic and regulatory differences between humans and our close evolutionary relatives, with the long-term goal of identify the genetic basis of human-specific traits, including genetic variation that underlies higher susceptibility to certain diseases and disorders in humans than in other primates. Gilad’s work is funded by several federal grants to study genetic variation in humans and close evolutionary relatives.
