It’s a dystopian story that takes place in 2027 about a world on the brink of the end of civilization. Women for some reason have become infertile, and, consequently, humanity is facing extinction. A single woman is found who has miraculously become pregnant and the film revolves around protecting her to save the future of the human race.
Unlike “The Children of Men,” Zhang’s report on the near-extinction of the Down syndrome (DS) people in Denmark isn’t dystopian at all. It’s cruel and real, and spreading to a country near you. While dystopian storytelling has rendered civilization extinct due to women’s infertility, prenatal genetic testing has rendered a particular kind of child extinct by snuffing out their lives before they are even born.
In 2004, the Danish government, taking advantage of this discovery, made prenatal genetic screening available to every pregnant woman, regardless of her age or any particular risk factors. There is a noticeable shift from tests and technologies being used without any medical indication for their use.
With DS, there is no therapy or cure, so I often call prenatal genetic screening, “search and destroy.” It’s one thing to take a test to find an illness for which there is a treatment, but a wholly different thing to be testing to find things where no treatment exists, or in this case, the so-called treatment is termination.
Prenatal genetic testing occurs not only during pregnancy, but often on embryos created in the laboratory. This step of assisted reproduction is to be certain that the embryos the parents want are transferred into the uterus in order to have a child of one’s choosing.
These are often referred to as “designer babies” because they are designed and chosen based on desirable characteristics (boys over girls) or are NOT selected because of undesirable outcomes such as DS.
The recent completion of the DNA sequence of human chromosome 21 has provided the first look at the 225 genes that are candidates for involvement in DS. A broad functional classification of these genes, their expression data and evolutionary conservation, and comparison with the gene content of the major mouse models of Down syndrome, suggest how the chromosome sequence may help in understanding the complex phenotype.
Since the Danish began testing pregnant women in 2004, the number of pregnancies in which DS was detected and then aborted are staggering. Sadly, the majority of parents in Denmark have chosen to terminate the pregnancy when DS is suspected. Zhang reports that in 2019, there were only seven children born in Denmark with DS.
She adds that “eleven other babies were born to parents who either declined the test or got a false negative, making the total number of babies born with DS last year 18.”
