Congenital Glucose–Galactose Malabsorption Presenting as Hypertriglyceridemia and Medullary Nephrocalcinosis

Year: 2025

Type: article

Abstract: A 4-month-old male child was admitted with failure to thrive, persistent osmotic diarrhea, and presence of multiple metabolic abnormalities, which included hypertriglyceridemia, hypercholesterolemia, hypercalcemia, and medullary nephrocalcinosis. He was diagnosed with congenital glucose–galactose malabsorption (CGGM). The exome analysis showed presence of pathogenic mutation in exon 8 of the SLC5A1 gene (c875G>A, p.Cys292Tyr). This gene codes for a sodium–glucose cotransporter called SGLT1. To date, no clinical case reports have reported hypertriglyceridemia and hypercholesterolemia with CGGM. Hypercalcemia and medullary nephrocalcinosis have also been reported only in a handful of CGGM cases worldwide. Through this case, the authors attempt to highlight the uncommon manifestation of this rare disease to facilitate timely management. Although the child died due to healthcare-associated infection (HCAI), pre-natal counseling of the family was carried out for the management of future pregnancies.
