Pioneering doctor given ‘venerable’ title

ROME — A French doctor who discovered the genetic basis of Down syndrome but spent his career advocating against abortion as a result of prenatal diagnosis has taken his first major step to possible sainthood.

Pope Francis on Thursday approved the “heroic virtues” of Dr. Jerome Lejeune, who lived from 1926 to 1994 and was particularly esteemed by St. John Paul II for his anti-abortion stance.

The papal recognition of Lejeune’s virtues means he is considered “venerable” by the Catholic

Church.

The Vatican must now confirm a miracle attributed to his intercession for him to be beatified and a second one for him to be declared a saint.

According to his official biography, Lejeune in 1958 discovered the existence of an extra chromosome on the 21st pair during a study of the chromosomes of a child. It was the first time scientists had found a link between an intellectual disability and a chromosomal anomaly; the condition is now known as trisomy 21.
