A scientist saint?

By Beryl Lieff Benderly, February 24, 2015 (Science Careers; DOI: 10.1126/science.caredit.a1500051) — Winning a prestigious science prize can be the capstone of an outstanding career. But one distinguished researcher, we recently learned, is a candidate for a major honor rarely bestowed on a scientist: canonization as a saint in the Roman Catholic Church.

Afterward, he reportedly told his wife, “Today, I lost my Nobel Prize in medicine.”

Were French geneticist and physician Jérôme Lejeune to be so recognized, it would not be for his significant scientific accomplishments but for his position on an ethical issue that grew out of that work—a position he apparently believed damaged his standing in the scientific world and his chance of winning its most coveted prize. Whether this is true is difficult to judge, but fear of harming his scientific eminence did not dissuade Lejeune from expressing and acting on his convictions.

In 1958, 2 years after Joe Hin Tjio and Albert Levan of the University of Lund in Sweden established that human beings normally have 23 pairs of chromosomes, Lejeune discovered that trisomy 21—the presence of an extra copy of chromosome 21—causes Down syndrome, a condition characterized by intellectual deficits, characteristic physical features, and often other health problems. Lejeune went on to become a professor of fundamental genetics in the medical faculty at the University of Paris and research director at France’s National Center for Scientific Research for 30 years. He identified several other chromosomal abnormalities associated with particular syndromes.

Among other honors, in 1969 Lejeune received the William Allan Memorial Award, the American Society of Human Genetics’s top prize, bestowed annually in recognition of “substantial and far-reaching scientific contributions to human genetics,” according to the society’s website. Lejeune was the first person to win “for accomplishments in human cytogenetics. The startling growth of this young discipline over the past decade is intimately association with [his] contributions,” the prize citation states.

It was a bitter irony for Lejeune, then, when the “young discipline” spawned by his research permitted the diagnosis of Down syndrome in utero, facilitating the termination of affected pregnancies. A devout Catholic who staunchly opposed abortion, Lejeune hoped that research into the causes of Down syndrome and other genetic disabilities could lead to improved treatment and even cures. He was active in treating Down syndrome patients, counseling their families, and advocating against abortion. In 1994, Pope John Paul II appointed him founding president of the Pontifical Academy for Life.

Lejeune’s views were well known in the scientific world. At the William Allan Memorial Award ceremony, instead of presenting the customary lecture on research, Lejeune gave a talk called “On the Nature of Men,” during which he noted that “geneticists have not broken the secret of the human condition, and … scientific arguments are of little help in ethical issues.” He ended with an impassioned rejection of genetics as a basis for terminating pregnancies. Afterward, he reportedly told his wife, “Today, I lost my Nobel Prize in medicine.”

In 2007, the Roman Catholic Archdiocese of Paris undertook the first step in the process of canonization. It completed that stage in 2012, and Lejeune’s cause moved to Rome. Now the Vatican will determine whether the next steps toward canonization are warranted. It has been suggested that he could eventually become the patron saint of people with Down syndrome.

For whatever reason, Lejeune, who died in 1994, never got the call from Stockholm.
