Early life and education

Beaudet was born in Woonsocket, Rhode Island.^[5] He was educated at the College of the Holy Cross, where he received a Bachelor of Science (B.S.) in biology, magna cum laude, in 1963. He then earned a Doctor of Medicine (M.D.), cum laude, from Yale Medical School in 1967.^[6]

Beaudet 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

Beaudet began his research in the 1960s with studies on protein synthesis.^[1] 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.^[5] His group co-discovered that the UBE3A gene was inactivated as the cause of Angelman syndrome,^[9] and that deletion of the snoRNAs likely contributes to the Prader-Willi phenotype.^[10] 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.^[11]

Beaudet has published research on the possible association between the deficiency of a carnitine biosynthesis gene and risk of autism in boys,^[12] and has contended that some of these cases of autism may be preventable through carnitine supplementation.^[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] 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.^[16][17]

Beaudet has been a principal investigator at the Howard Hughes Medical Institute.^[18]
