If my fiancée is blind, could our future kids inherite blindness?

Answer 1

It depends on the reason for the blindness, and which genes are involved. You should talk to a genetic counsellor if you are concerned.

Answer 2

Of what I know there is a certain inherited disease that produces blindness to offspring.
Its called Leber congenital amaurosis (LCA)
The disease is often cause by mutations in the GUCY2D gene

Two faulty GUCY2D genes, the cells at the back of the eye are unable to respond properly to light, and therefore cannot send proper visual signals to the brain. Individuals who suffer from this disorder typically become blind in infancy.

Im not sure if Gene theraphy is yet available,but consider its just a slight chance, half of the chromosomes will be from your fiancée and the other yours,this might give the opportunity of only one faulty gene to transfer,the proper care and doctors aid will help your infant through.

Hope it helps

Answer 3

That would depend on the root cause of your fiancee's blindness. If he is blind due to a genetic cause and born with it yes, it probably it hereditary, or did he suffer an injury or accident that caused the blindness if so then it would not be hereditary.

Answer 4

If his blindness is genetic and some of his family as well are blind or have something like that wrong, if something happened to him to make that happen then there shouldn't be a problem

PS: i think thats great of you to see past that.

Answer 5

Is your fiancee' blindness hereitary? Its impossible to answer your question as it is stated. What was the cause of the blindness in the first place.

Answer 6

Only if his blindness is genetic in origin, and only then if it's a dominant gene (as opposed to a recessive one) or if it's recessive and you happen to carry the same recessive gene.

Answer 7

yes it is possible, i'd say a 50/50 % chance depends on who's genes are stronger

Answer 8

if his genes are to high of it maybe yes... if not now... maybe on the next generation...
