- dekhn 5y agoYour example is "genetic" testing- it only samples a limited number of locations in the genome. This method is more like whole genome sequencing.
- abcc8 5y agoThere really aren't that many reasons to sequence the entire genome in this context. Specific disease causing mutations in the parents can be specifically targeted in the embryo/fetus. Similarly, PRS scores don't require full genome sequencing to generate (but also aren't ready for prime time routine usage). Also, aneuploidy detection doesn't require genome sequencing. This is just a few examples.
- dekhn 5y agoI was just pedantically correcting the person I was replying to.
- Metacelsus 5y agoThis method is similar, but uses the parents' genomic data to improve predictions of the embryo's genome (since sequencing only a few cells gives low-quality data).
