Galactosemia was the second disorder found to be detectable through newborn screening methods by Robert Guthrie. [3] Its incidence is about 1 per 60,000 births for people of European ancestry. In other populations the incidence rate differs. Galactosemia is about one hundred times more common (1:480 births) [4] in the Irish Traveller population ...
In classic galactosemia, galactose-1-phosphate uridylyltransferase activity is reduced or absent; leading to an accumulation of the precursors, galactose, galactitol, and Gal-1-P. [3] The elevation of precursors can be used to differentiate GALT deficiency from galactokinase deficiency, as Gal-1-P is typically not elevated in galactokinase ...
If this second result is still in the normal range, the child is said to have passed their galactose challenge, and dietary galactose restrictions are typically relaxed or discontinued. If the second test shows elevated Gal-1P levels, the parent/guardian may be advised to resume galactose restriction for the child, and the challenge may be ...
Approximately 70% of galactosemia-causing alleles have a single missense mutation in exon 6. A milder form of galactosemia, called Galactokinase deficiency, is caused a lack of the enzyme uridine diphosphate galactose-4-epimerase which breaks down a byproduct of galactose. This type of is associated with cataracts, but does not cause growth ...
Galactosemia is an autosomal recessive inherited disorder detectable in newborns and childhood. [12] It occurs at approximately 1 in every 40,000-60,000 live-born infants. Classical galactosemia (G/G) is caused by a deficiency in GALT activity, whereas the more common clinical manifestations, Duarte (D/D) and the Duarte/Classical variant (D/G ...
Contraindications to breastfeeding are those conditions that could compromise the health of the infant if breast milk from their mother is consumed. Examples include galactosemia, untreated HIV, untreated active tuberculosis, Human T-lymphotropic virus 1 or II, uses illicit drugs, or mothers undergoing chemotherapy or radiation treatment.

Is the most problematic, as galactose-free diets are not effective in treating neurocognitive deficiencies (in particular language disorders such as verbal dyspraxia) and ovarian failure. If a galactose-free diet is administered, cataracts and acute symptoms such as kidney and liver failure respond immediately.
