Ethical issues
Of course, this technological achievement raises ethical issues. “What do we do with the genetic data obtained at birth that won’t become apparent until adulthood, if we find a BRCA1 or BRCA2 variant in a newborn’s genome?” asked Dr. Genevieve.
Will the information obtained be stored somewhere? “This is a real issue,” he said. “The English have a national system. In their newborn screening program, when an infant grows into adulthood, he or she can have access to the genetic data.”
There is also a big risk that women will be pressured to undergo genetic testing during pregnancy. “No genome-related antenatal tests are carried out unless there are concerning ultrasound findings and only to look for particularly severe incurable diseases,” said Dr. Geneviève.
Not like Gattaca*
Financial obstacles should be quickly pushed aside. The cost of genome sequencing has decreased in the past few years. The first sequencing in 2003 cost close to $3 billion. Nowadays, it can be done for less than 1,000 € (just over $1,000).
Although neonatal genetic screening would enable us to limit the development of serious diseases, the decision to use such testing routinely must be made by society as a whole, Dr. Geneviève concluded.
“We often oppose preventive and personalized treatment strategies. Now the two have joined forces,” said Pascal Pujol, MD, PhD, chair of SFMPP.
For Dr. Pujol, broadening the application of genome sequencing is a no-brainer. “It won’t be like in Gattaca,” he reassures us. “It wouldn’t be done to determine a person’s character but [rather] to prevent those rare diseases that affect 4 to 5% of the population.”
