We just found out this morning after 3 months of tests that my 4 month old (at present unsymptomatic) has two CF mutations. I am in the science field and can find nothing about
the second mutation they found "D1154N" does anyone have any info on the symptoms/severity associated with this mutation. He is deltaF508 (tons of info available on that) and D1154N.
He was tested at birth and came back positive for dF508, then his sweat tests were borderline, his fecal elastase is normal but he has elevated serum trypsinogen for an infant. He is gaining weight and growing at above normal for his age and has been very healthy with a runny nose for a month (probably normal for a daycare baby).
I am still in a daze over this. Any advice to find info on D1154N?
