SLC5A1 Variants in Turkish Patients with Congenital Glucose-Galactose Malabsorption

چکیده
Congenital glucose-galactose malabsorption is a rare autosomal recessive disorder caused by mutations in SLC5A1 encoding the apical sodium/glucose cotransporter SGLT1. We present clinical and molecular data from eleven affected individuals with congenital four unrelated, consanguineous Turkish families. Early recognition timely management eliminating glucose galactose diet are fundamental for to survive develop normally. identified novel missense variants, p.Gly43Arg p.Ala92Val, which were linked disease two Stable expression CaCo-2 cells showed that p.Ala92Val variant did not reach plasma membrane, but was retained endoplasmic reticulum. The variant, however, displayed processing membrane localization comparable wild-type Glycine-43 displays nearly invariant conservation relevant structural family of cotransporters exchangers, localizes SGLT1 transmembrane domain TM0. represents first disease-associated TM0; role TM0 function has been established. In summary, we expanding mutational spectrum this disorder.

Congenital glucose galactose malabsorption.
Introduction Congenital glucose galactose malabsorption (CGGM) is a rare autosomal recessive disorder, which presents as a protracted diarrhoea in early neonatal life. It is due to a defect in sodium coupled transport of glucose and galac tose in the enterocyte (1). Diarrhoea in CGGM is osmotic, caused by accumulation of unabsorbed glucose and ga lactose in the intestine (2), which results in...

متن کاملCongenital Glucose-Galactose Malabsorption: A Case Report.
Congenital glucose-galactose malabsorption (CGGM) is a rare cause of intractable infantile diarrhea, with only a few hundred cases recognized worldwide. This life-threatening disorder must be considered in the differential diagnosis of an infant who presents with diarrhea and dehydration that fails to respond to standard therapy. The clinical and diagnostic course of an infant with recurrent ep...
