It is complicated. If it is due to a flaw in one of the X or Y chromosomes, that greatly changes the calculation. Dominant/recessive categories changes the math.

But ignoring all that, it seems like you have the same risk as your parents: for them, there is a 50% chance they got it from one known carrier; for you, there is a 25% change of having gotten it from each of two known carriers.
