Genetic Screening Via IVF
A young British couple recently underwent in vitro fertilization and are now 14 weeks pregnant. What makes them different from every other IVF couple is that they are perfectly fertile. They underwent IVF to conceive a fetus guaranteed not to carry a specific breast cancer gene. While the BRCA-1 or BRCA-2 genes only account for 5% of breast cancers, women who carry the gene have a 50-80% chance of developing breast cancer. The husband family has a devastating history with breast cancer because of the gene in question and the couple took steps to make sure their daughter wouldn’t suffer the same fate. Five of the eleven embryos were free of the breast cancer gene, two were implanted and one developed into a fetus. Two of the other embryos were frozen for later use. This has been heralded a success by the medical community but naturally raises ethical questions such as where this will lead and if couples will be choosing designer babies rather than letting things happen naturally.
