Hello, just found out that one of my 34 week born twins showsw1089x with Variant TG12-5T/TG11-7T. We have 4 other boys that have had the same screening with no results as carriers. My question is, did this sound normal? And if so, does this mean he has cf? Or just a carrier? Kinda confused. Getting tested next week but weird that none of my other kids showed as carriers. Your help is very much appreciated.
