Tell me about your situation:
If you are caused by drugs, then there is no inheritance, so children will not be affected.
If you are caused by a genetic disease, it should be recessive. Although your parents are not sick, they are both carriers. Your husband is healthy, but I'm not sure if he is a carrier.
If he is not a carrier (there is a high probability that he is not a carrier), then your child will certainly not get sick.
If he is a carrier, your child has a 50% chance of getting sick.
Finally; Even if the child has multiple fingers, it can still be removed when the child is about 3 years old.
