D28G MUTATION IN CONGENITAL GLUCOSE-GALACTOSE MALABSORPTION

Background: Congenital glucose-galactose malabsorption is a rare autosomal recessive disorder of the intestinal transport of glucose and galactose, leading to watery diarrhea, dehydration, failure to thrive, and early death. Methods: In this study, we analyzed D28G mutation in 16 family members of a patient with typical presentation of congenital glucose-galactose malabsorption with polymerase chain reaction-Restriction Fragment Length Polymorphism method. Results: Nine members of this family were heterozygous for D28G mutation.
