Re: CMT and children/Pre-Implantation Genetic Diagnosis

[Guest guest]

Carmella,

The procedure you are referring to is called Pre-Implantation Genetic

Diagnosis, it is available for some types of CMT, not all. I think I

have something in our Files about this, maybe in the Pregnancy folder.

I've done some research into pre-implantation genetic diagnosis. They

can't " remove " the CMT gene. They can't test for the CMT gene in sperm, but they

can test fertilized or unfertilized eggs for the presence of the genetic

mutation.

Then they separate the unaffected eggs without the mutation from the affected

eggs with the mutation. Supposedly, there's a 50/50 shot of passing on CMT,

which means, theoretically, half of the eggs from a woman with CMT will carry

the mutation, and half will not.

Personally, I have an opinion that the odds for passing on CMT are higher than

50/50. I've just finished a bunch of Biology, icrobiology, Pathophysiology, and

Anatomy and Physiology classes, all of which dealed somewhat with genetics, and

fueled even more my personal interest in this subject.

Oh for years I have thought that the rate is much greater than 50/50

too.

Vanzern, That's for the information. 50/50 seems like a low number

considering how many of us have CMT children.
