thanks alot for your reply foufoka . but I dont yet understand the benefit of genetic test . because you said that with this test you can predict the severity of the disorder . but I know that my child have pku and no test can reduse the severity of disease , just he should have a diet to control his pku .
and if we want to have another child again this test cant help us , because we are the carrier of this defect . and in every pregnancy , we have 25 percent the chance of having a pku child .
So, I think doing genetic test for the family such us is wasting the time .
