Arthur L. Beaudet is an American physician. He is a past 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[1] and into the National Academy of Sciences in 2011.

Early life and education[edit]

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.[5] He retired from Baylor in January 2020.

Research[edit]

Beaudet began his research in the 1960s with studies on protein synthesis.[2] 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.[6] In 1988, Beaudet's laboratory published a paper regarding the mechanism by which uniparental disomy might cause certain types of human genetic disease.[7] This paper proposed four mechanisms for uniparental disomy, each of which has since been shown to occur.[5] His group co-discovered that the UBE3A gene was inactivated as the cause of Angelman syndrome,[8] and that deletion of the snoRNAs likely contributes to the Prader-Willi phenotype.[9] In collaboration with Isis (now Ionis) Pharmaceuticals he demonstrated that oligonucleotides could be used to activate the paternal allele of Ube3a in the mouse as a possible therapeutic correction in Angelman syndrome.[10]

More recently, Beaudet has published research on the possible association between the deficiency of a carnitine biosynthesis gene and risk of autism in boys,[11] and has contended that some of these cases of autism may be preventable through carnitine supplementation.[12] 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.[13][14] Beaudet has worked for over a decade trying to develop a commercial form of cell-based noninvasive prenatal testing using fetal cells in the mother’s blood during the first trimester.[15][16] He now pursues this goal at Luna Genetics.
