Hi, I had gone through your question and understand your concerns. It is very difficult to comment with such a little information as muscular dystrophies are a group of unrelated diseases, each transmitted by a different genetic trait. Most likely your child is suffering from Duchenne muscular dystrophy which is transmitted as X-linked recessive trait , most likely inherited from your wife ( carrier for disease) and in that case there are 50 percent chances of your children affected ( male having disease and female being a carrier ). On a positive side there is 50 percent chances of having a normal baby , but chances are like head and tail , although chances are 50 percent of coming head or tail , but any can come any number of times. So I suggest you to get proper genetic counseling and diagnosis of disease with full family history to reach a conclusion and then make an informed decision. If planning for next pregnancy prenatal diagnosis is possible as early as the 12th wk of gestation by sampling chorionic villi for DNA analysis by Southern blot or PCR , decision to abort fetus can be taken if affected. Hope this answers your question. If you have additional questions then please do not hesitate in writing to us. Take care. • DISCLAIMER: - All the information provided here is for information purpose only , it is not a substitute for the advice of a physician after physical examination , it is not intended to replace your relationship with your doctor.
