WebJan 28, 2024 · Type I (classic) galactosemia, galactose 1-phosphate uridylyltransferase (GALT)-deficiency is a hereditary disorder of galactose metabolism. The current therapeutic standard of care, a galactose-restricted diet, is effective in treating neonatal complications but is inadequate in preventing burdensome complications. WebGalactose-1-phosphate is toxic and accumulates in liver and other organs, causing liver failure in early infancy. The usual presentation is hypoglycemia and encephalopathy in the first few days of life. Vomiting, diarrhea, jaundice, and failure to thrive are common.
