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.

CONCLUSIONS

To the best of our knowledge this is the first report of D28G mutation in Iran. Moreover, this simple typical PCR-Restriction Fragment Length Polymorphism method, allows immediate identification of D28G mutation.
