1 ABSTRACT 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 ...

This study assesses the efficiency of the galactosemia add-on test in neonatal screening performed on regular Guthrie card blood spots. Based on estimated average incidence of galactosemia (1:19,984 newborns) in São Paulo State, Brazil, the study develops a cost-benefit analysis model, using a B/C ratio and a 9.25% annual interest rate in order to decapitalize the results. Sensitivity analysis ...

UNLABELLED Newborn screening for galactosemia has shown a high prevalence of partial galactose uridyl transferase deficiencies such as Duarte (DG) galactosemia. STUDY OBJECTIVE To determine whether (a) there is any clinical impact of DG galactosemia on development (b) there is a relationship between outcome and biochemical parameters in patients who receive no treatment. STUDY POPULATION Tw...

The present study was designed to examine the development of structural changes, characteristic of diabetic neuropathy, in chronic galactosemia and their responsiveness to inhibition of the polyol-pathway. Sprague-Dawley rats weighing 70-90 g were given a 50% galactose diet continued for 4 or 8 months. Half of these animals were simultaneously given the aldose reductase inhibitor (ARI) WAY 121-...

BACKGROUND The aim of the study was to research concerning the epidemiology of newborns' galactosemia during 2007-2008 to find out whether screening was necessary for Iranian newborns or not and also what the symptoms of this disease before or after diet were. METHODS The data were collected from 24000 newborn babies from Fars Province, southern Iran. The enzymatic calorimetric test was done ...

PURPOSE Classic galactosemia is an inherited metabolic disease resulting from galactose-1-phosphate uridyltransferase (GALT) deficiency. Dietary lactose exclusion reverses many clinical manifestations of acute phase of the disease. Unfortunately most of the patients, despite dietary treatment, develop long-term complications among them disturbances of bone mineralization resulting in decrease o...

Purpose To test the hypothesis that children with classic galactosemia and speech disorders are at risk for co-occurring strength and coordination disorders. Method This is a case-control study of 32 children (66% male) with galactosemia and neurologic speech disorders and 130 controls (50% male) ages 4-16 years. Speech was assessed using the Percentage of Consonants Correct (PCC) metric from r...

BACKGROUND The objective of this study was to document the clinical, laboratory and genetic features of galactosemia in patients from the Cape Town metropolitan region. METHODS Diagnoses were based on thin layer chromatography for galactosuria/galactosemia and assays of erythrocyte galactose-1-phosphate uridyltransferase (GALT) and galactokinase activities. Patients were screened for the comm...

OBJECTIVE To assess feasibility and recall rates for newborn screening for congenital hypothyroidism, galactosemia and biotinidase deficiency in a predominantly rural and inner city population in and around the City of Lucknow in Uttar Pradesh, India. DESIGN Prospective observational study. SETTING Two tertiary-care and 5 district hospitals in and around Lucknow. PARTICIPANTS All babies b...
