Galactosemia is a genetic disorder which causes inability to metabolize galactose in the body. Our body converts galactose into glycolytic intermediate by Leloir pathway. Galactosemia is caused by the mutation in the gene encoding enzymes of Leloir pathway or non-functioning of these enzymes. Types of galactosemia are due to different enzyme deficiencies. Type I is for GALT (galactose-1-phospha...

Classic galactosemia is a genetic disorder that results from profound loss of galactose-1P-uridylyltransferase (GALT). Affected infants experience a rapid escalation of potentially lethal acute symptoms following exposure to milk. Dietary restriction of galactose prevents or resolves the acute sequelae; however, many patients experience profound long-term complications. Despite decades of resea...

BACKGROUND Classic galactosemia (OMIM 230400) is an inherited disorder in the metabolism of galactose caused by deficiency of the enzyme galactose 1-phosphate uridyl transferase (EC 2.7.7.12). Galactosemia leads to accumulation of galactose and galactose 1-phosphate (gal-1-P) in blood and tissues and, if untreated, produces neonatal death or severe mental retardation, cirrhosis of the liver, an...

AIM Galactosemia is a carbohydrate metabolism disorder with autosomal recessive inheritance. The most frequent enzyme deficiency is galactose-1-phosphate-uridylytransferase, which causes classic galactosemia. When the enzyme is absent, an infant cannot metabolize galactose-1-phosphate and it cumulates in liver, kidney, brain, tongue, lens, and skin. This study aimed to evaluate the clinical and...

The pathologic consequences of various inborn errors of metabolism in the conversion of dietary and endogenously produced galactose through the Leloir pathway have recently been reviewed (1, 2 ). In this issue of the Journal, Ficicioglu and colleagues (3 ) report that children (ages 1– 6 years) who have Duarte galactosemia (DG), a variant form of galactosemia, and are on a standard diet have ty...

Cerebral edema resulting in elevated intracranial pressure is a well-known complication of galactosemia. Lumbar puncture was performed for the diagnosis of clinically suspected bacterial meningitis. Herniation of cerebral tissue through the foramen magnum is not a common problem in neonatal intensive care units because of the open fontanelle in infants. We present the case of a 3-week-old infan...

INDIAN PEDIATRICS 19 VOLUME 53__JANUARY 15, 2016 he incidence of classical galactosemia in different countries has been reported to vary from 1 in 30,000 to 1 in 75,000 [1]. The exact population incidence in India is not known as mutations and importance of GALT gene analysis in the diagnosis of galactosemia in Indian patients. The same study also revealed that the mutational profile amongst In...

OBJECTIVE To report a case of classic galactosemia that presented with a rare ocular finding, Peters' anomaly. CLINICAL PRESENTATION AND INTERVENTION A neonate, born to first-degree healthy cousins, presented with persistent vomiting, failure to thrive, lethargy, and jaundice. Corneal opacity was noticed in the left eye. Hydration and empiric antibiotics were started after collection of the r...

Classic galactosemia is a human autosomal recessive disorder caused by mutations in the GALT gene (GAL7 in yeast), which encodes the enzyme galactose-1-phosphate uridyltransferase. Here we show that the unfolded protein response pathway is triggered by galactose in two yeast models of galactosemia: lithium-treated cells and the gal7Δ mutant. The synthesis of galactose-1-phosphate is essential t...
