Reply to comment by LoverlyRails in In a first, doctors treat fatal genetic disease before birth by 29PiecesOfSilver

They are usually able to detect the mutated gene from the mother via genetic sequencing and the same with the father, so they can determine exactly where the mutation occurs in both sets of DNA. They then build a probe to detect this mutation on a small sample of the embryo. The only time I’ve heard of the probe failing is if the parents were closely related. So it’s likely that they can do this via IVF. Source: did IVF with genetic testing for an autosomal recessive disease

Mildly worth noting:

While relatively straight forward from a research-project standpoint, I'd be impressed to see that done clinically with less than a six-digit pricetag.

Yes, absolutely. IVF is not cheap and unfortunately insurance does not cover it most of the time (in the US). The genetic testing on top of the IVF for my case was an additional $6,800. Typically a round of IVF could cost anywhere from 15-25k, depending on medications, clinic, additional surgical procedures, etc. it’s not very accessible in the US.

This couple is in Ontario so they likely paid very little if anytime at all.

There are some genetic diseases that are are extremely difficult if not impossible to detect. I know of a case where the parents were not at all related but lost two children at a year old to a genetic disease which was undetectable. It really is a harrowing world.

No, this is at the DNA level so it's pretty straightforward.

And in case you are wondering, I am a PhD doctor and DNA/genetic testing is in my field of expertise.

...And my guess is the same can be said of someone whose handle is a play on "Oligos", which are synthetic DNA building blocks for this kind of work.

Their name is a twist on oligodendrocytes, which are a type of glial cell.
