- Abstract
We carried out molecular screening for mutations in the cystic fibrosis transmembrane regulator (CFTR) gene in eight children of Sardinian descent seen because of hypotonic dehydration associated with hyponatremia, hypochloremia, hypokalemia, and metabolic alkalosis; none had pulmonary or pancreatic involvement. All the patients had the T3381 mutation either in homozygosity or compound heterozygosity with another CF mutation. The T3381 mutation was not detected in patients with CF who had classic symptoms or in healthy persons of the same descent. These data suggest that the T3381 mutation is associated with a specific mild CF phenotype.
