Arthur L. Beaudet is a professor and chair of molecular and human genetics at Baylor College of Medicine. He was inducted into the Institute of Medicine in 1995,[4] the Society of Scholars in 2008[2] and into the National Academy of Sciences in 2011.[5]

Early life and education

Beaudet was born in Woonsocket, Rhode Island. He received a bachelor's degree from the College of the Holy Cross in 1963 and received his MD from Yale Medical School in 1967. He completed a residency in pediatrics at Johns Hopkins Hospital in 1969 and a postdoctoral fellowship at the National Institutes of Health two years later. After his NIH fellowship ended in 1971, Beaudet began his affiliation with Baylor.[6]

Research

Beaudet began his research in the 1960s with studies on protein synthesis.[3] In the 1970s, Beaudet et al. demonstrated mutations in cultured somatic cells; he has also conducted much research on inborn errors of metabolism, particularly urea cycle disorders.[7] In 1988, Beaudet's laboratory published a paper regarding the mechanism by which uniparental disomy might cause certain types of human genetic disease.[8] This paper proposed four mechanisms for uniparental disomy, each of which has since been shown to occur.[6] In the late 1980s and early 1990s, Beaudet worked on developing a screening test for cystic fibrosis.[9]

More recently, Beaudet has published research on the possible association between the deficiency of a carnitine biosynthesis gene and risk of autism in boys,[10][11] and has contended that some of these cases of autism may be preventable through carnitine supplementation.[12][13] Beaudet has also developed a test which enables doctors to detect whether or not a child was conceived as a result of incest without testing either parent.[14][15] Other disorders Beaudet's lab conducts research on include Prader-Willi syndrome and Angelman syndrome.[5] Beaudet led the decision by Baylor to acquire a DEPArray™ system from Silicon Biosystems in 2011 for use in his research; Beaudet hopes to use the technology to collect fetal cells from the mother's blood for testing as opposed to collecting them using amniocentesis, which is more invasive and dangerous.[16]
