Met470Val on 7T
Hello to everyone!
My Son is three, had a mystery diagnosis since a baby. He had a Bronchoscope in March this year. The Polmonologist cleaned out his lungs and told me he looked like he has Cystic Fibrosis. But the sweat test came back negative. He was recently tested positive for having Met470Val 7T. He tested positive for two copies of this polymorphism. Does this mean he has A Typical CF or what?
