FISIOPATOLOGIA GALACTOSEMIA PDF

Galactose Lactose in food such as dairy products is broken down by the enzyme lactase into glucose and galactose. In individuals with galactosemia, the enzymes needed for further metabolism of galactose Galactokinase and galactosephosphate uridyltransferase are severely diminished or missing entirely, leading to toxic levels of galactose or galactose 1-phosphate depending of which enzyme is missing in various tissues as in the case of classic galactosemia , resulting in hepatomegaly an enlarged liver , cirrhosis , kidney failure , cataracts , vomiting , seizure , low blood sugar hypoglycemia , lethargy , brain damage , and ovarian failure. Galactosemia is inherited in an autosomal recessive manner, meaning a child must inherit one defective gene from each parent to show the disease. Heterozygotes are carriers, because they inherit one normal gene and one defective gene.
