Victor McKusick's Study of the Amish

Victor A. McKusick (October 21, 1921 – July 22, 2008) was an American physician, geneticist, and educator, widely regarded as the father of medical genetics. He spent his professional life at the Johns Hopkins Hospital and the Johns Hopkins University School of Medicine, where he was University Professor of Medical Genetics and Professor of Medicine. McKusick's pioneering research and his leadership in the field have had a profound impact on how genetic disorders are understood and treated today.

Early Life and Education

Victor Almon McKusick was born in Parkman, Maine, the son of a country doctor. He initially enrolled at Tufts University to study engineering but transferred to Johns Hopkins University after being inspired by the work of Dr. William Osler. He earned his medical degree from the Johns Hopkins University School of Medicine in 1946. Following his graduation, McKusick completed his residency in internal medicine at Johns Hopkins Hospital.

Career and Contributions

In the early 1950s, McKusick began to focus on genetics, a field that was not yet widely recognized in medicine. He was particularly interested in the genetic aspects of cardiovascular diseases and connective tissue disorders. His work led to the identification of Marfan syndrome as a connective tissue disorder and contributed significantly to the understanding of this condition.

McKusick's interest in genetics expanded beyond specific diseases to encompass the entire human genome. He was instrumental in the development of the field of medical genetics and played a key role in mapping the human genome. In 1966, he published the first edition of Mendelian Inheritance in Man (MIM), a comprehensive catalog of all known genes and genetic disorders. This work, which has been updated continuously and is now available online as Online Mendelian Inheritance in Man (OMIM), remains an essential resource for researchers and clinicians.

Throughout his career, McKusick advocated for the integration of genetics into medical practice and education. He founded the Division of Medical Genetics at Johns Hopkins in 1957, one of the first such programs in the world. He also established the Short Course in Medical and Experimental Mammalian Genetics at The Jackson Laboratory in Bar Harbor, Maine, which has trained thousands of geneticists from around the world.

Awards and Honors

McKusick received numerous awards and honors for his contributions to medicine and genetics, including the National Medal of Science in 2002, the Lasker Award in 1997, and the Japan Prize in 2008. He was a member of the National Academy of Sciences and the American Philosophical Society.

Legacy

Victor A. McKusick passed away on July 22, 2008, but his legacy lives on through his contributions to medical genetics. His vision for the integration of genetics into clinical medicine has transformed the field and has led to significant advances in the diagnosis, treatment, and prevention of genetic disorders. McKusick's work laid the foundation for the Human Genome Project and the field of genomics, revolutionizing our understanding of human biology and disease.
