Ok so this is the one that runs in our family. So there is a 50% chance that I carry the gene - that is what I thought.X-linked recessive inheritance is when the mother passes on one faulty X chromosome (See figure below). The resulting child, male or female, has a 50% chance of inheriting the faulty gene but only the male can develop MD from it. Because the female child has two X chromosomes, one healthy X can override one inherited faulty X. In this instance however, the female child is still a carrier of the inherited faulty X and may pass it on to her children. The female child should have genetic testing to determine her status before having her own children.
So if I am tested and it is proven that I carry the gene, then there is a 50% chance of passing on that gene to my son who could then become sick with the illness later in life. Is that right?
I looked up the gender selection/IVF and you obviously have to qualify to be able to have this done (in some places they have canned it all together). Even then - isn't that majorly messing with mother nature?
On the flip side though - if I chose not to get tested and went ahead and concieved a boy, I would have knowingly put that child at risk.
