History of the MCW Linda T. and John A. Mellowes Center for Genomic Sciences and Precision Medicine
In 2017, the Mellowes Center ushered in a new era of genomics and precision medicine with the slogan "Beyond the Base Pairs." This phrase reflects the understanding that interpreting the genome involves much more than just sequencing it. The genome operates on multiple levels of regulation, and as shown here, the RAG complex plays a critical role in the immune system by modifying specific genome regions to generate antibody diversity. When RAG malfunctions, it can lead to immunodeficiency, autoimmune diseases, and blood cancers. Rather than focusing solely on genes themselves, our work delves into how the genetic code is tagged, packaged, regulated, and transformed into the molecular machinery essential for cellular function.
By expanding access to genetic testing, refining experimental design, and enhancing data interpretation, we aim to elevate research and pave new avenues for Precision Medicine, constantly forging the path toward a more advanced future.
Our Place in the History of Human Genomics
Mellowes Center Previous Directors
Allen W. Cowley, Jr., PhD
Dr. Allen W. Cowley, Jr. is a transformative leader at MCW, serving as Professor and Chairman of the Department of Physiology since 1980. Over his distinguished career, he authored nearly 400 scientific publications, significantly advancing our understanding of the kidney’s role in hypertension and chronic kidney disease.
Recognizing the growing importance of genomics in physiology, Dr. Cowley played a pivotal role in establishing the Human Molecular Genetics Center (HMGC) at MCW. As part of this effort, he strategically recruited Dr. Howard Jacob from MIT, bringing critical expertise in genetics that helped bridge the gap between genomic research and physiological function. This collaboration led to groundbreaking discoveries, including the first genomic map of cardiac, vascular, pulmonary, and kidney function, published in Science in 2001. Dr. Cowley’s laboratory also has made major contributions to understanding the regulation of medullary blood flow and sodium transport, uncovering key interactions between nitric oxide and superoxide that shape hypertension risk. To ensure the continuation and growth of the HMGC upon Dr. Jacob’s departure, Dr. Cowley again took up the mantle to recruit the current director, Dr. Raul Urrutia from the Mayo Clinic.
Through his scientific vision, mentorship, and strategic leadership, Dr. Cowley not only elevated MCW’s reputation as a leader in medical research but also laid the foundation for its advancements in genomics. His recruitment of Dr. Jacob and Dr. Urrutia were critical steps in the evolution of the Mellowes Center, continually preparing MCW for the next wave of genomic discovery.
Howard Jacob, PhD
Dr. Howard Jacob, a pioneering figure in genomic medicine, was recruited to MCW in 1999 to help bridge the gap between genomics and physiology. He was the Founding Director of the Human and Molecular Genetics Center (HMGC), where he led its transformation from a modest team of two faculty members to a world-class research center with 30 faculty. Under his leadership, HMGC became one of the top-funded genetic programs in the country, establishing MCW as a leader in genomic science.
Founded at the dawn of the Human Genome Project, the HMGC played a pivotal role in advancing genomic research and its applications in medicine. During Jacob's tenure, the center pioneered the use of whole genome sequencing to investigate gene variants linked to both rare and common diseases. These advancements laid the foundation for what would later become the Linda T. and John A. Mellowes Center for Genomic Sciences and Precision Medicine.
Dr. Jacob's team made history in 2009 when they became the first to use genomic sequencing to directly save a patient's life. This groundbreaking case involved 6-year-old Nicholas Volker, whose diagnosis and successful treatment demonstrated the real-world power of applying genomics in clinical care. This landmark achievement cemented MCW’s reputation as a global leader in translational genomics, bridging the gap between genetic discovery and patient care.
Following his time at MCW, Dr. Jacob continued advancing genomic medicine, first at the HudsonAlpha Institute for Biotechnology and later at AbbVie, where he has served as Vice President and Head of Genomic Research since 2018. Throughout his career, he has remained committed to translating genomic research into real-world medical applications, shaping the future of personalized medicine.
