Guest guest Posted July 22, 2000 Report Share Posted July 22, 2000 , Lamar here X linked CMT (or any other sex linked condition) is a much more complex subject, but here is how a carrier status develops. NOTE this is ONLY true with X-Linked and no other types of CMT. X-linked is one of the types that can be tested for. If the CMT parent is male and inherited his disease as sex-linked, his children would be disease free, but his daughters would be carriers. Those daughters would have a one in four chance of having a male child with CMT.

I was thinking more along the lines of CMT does not skip generations.

You can do gender selection from the beginning. Semen selection. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted July 22, 2000 Report Share Posted July 22, 2000 Hi, I have x-linked cmt and I understood the chance of haveing a child a bit different. There is a 50% chance that you will have a child with cmt. You could have a boy or a girl with cmt, or both genders without. If a girl has no cmt she is not a carrier anymore and the disease is stopped. In my family my grandfather gave cmt to my mother. Her brother has no cmt. I got it from my mother. If I will have a child the percentage is 50% of having a child without cmt. This is what my neurologist told me.

Guest guest Posted July 23, 2000 Report Share Posted July 23, 2000 , Lamar here, The information I gave was directly from links on CMTA's site. It is in accordance with standard X-linked heredity. You will note that if a MALE inherits X linked CMT, his sons would not have CMT, but his daughters would be carriers, and not have the disease. THEIR male children (the grandsons of the Male with CMT) would each have a 25% chance of having CMT. In addition, if a FEMALE inherits X-linked, HER children stand a 50% chance of each one having CMT, as you said. The pattern depends on the sex of the parent, and sex of the child. Males are XY getting an X from the mother and a Y from the father. Females are XX, getting an X from the mother and an X from the father. Therefore a male child gets the Y chromosome from the father, and the X from the mother. That is why a male can not pass on an X chromosome to a son. A female passes an X chromosome to either a her son or daughter. I hope this makes it more clear. X linked is easy to show on a blackboard but difficult to describe in words. When I can I will do a page with autosomally dominant, autosomally recessive, and X-linked, that should be easier to understand. But as you were told, you, being female, can not produce a carrier child. If you have a son with CMT, he can.
