Hey friends! Let’s chat about the exciting advancements in pre-implantation genetic screening and diagnosis. This area of assisted reproduction is buzzing with new technologies that are making a real difference in screening embryos. Not only can we now check for genetic diseases (known as PGD), but we can also assess for chromosome abnormalities (called PGS). With the remarkable progress in DNA biotechnology, companies like Gene Health Solutions from California have started using insights from the Human Genome Project to analyze DNA from single embryonic cells more effectively.
In the past, testing a single embryonic cell was limited – we could only check either for genetic mutations with a handful of markers or analyze chromosome numbers, but not both simultaneously. Excitingly, Gene Health Solutions has recently introduced methods that allow us to do both: checking for genetic mutations (especially if parents might pass on certain conditions) and chromosome copy numbers. This means we can rule out issues like Down syndrome and other chromosomal abnormalities that could lead to miscarriage or implantation failure. And guess what? This can all be done using the amplified DNA from just one cell!
We’re thrilled to be participating in pilot studies with this new technology, and due to its success, we’re now offering this testing regularly to couples who need it. This is such a game-changer because it enables us to not only choose healthy embryos but also gives us confidence that the embryos we select for transfer have the right chromosome numbers, increasing the chances of a successful pregnancy.
Examining Miscarriages with DNA Micro-Array Technology
Another fascinating application of DNA micro-array technology is in examining miscarriages for chromosome abnormalities. Previously, determining if a miscarriage was linked to chromosomal issues required a D&C procedure to collect placental DNA and then sending it to a lab, which could be a lengthy and uncertain process. Now, we can analyze placental tissue along with a blood sample from the mother. This means we can distinguish between maternal and fetal DNA, and we don’t need viable cells to get a result. This advancement allows us to better understand the causes of pregnancy loss, which is often due to chromosomal abnormalities.
There’s no doubt that these genetic technologies will keep evolving, becoming even faster and more accurate than they are today. It’s thrilling to be at the forefront of applying cutting-edge science to help our patients navigate their fertility journeys.
