Galactose epimerase deficiency has an autosomal recessive pattern of inheritance.. Galactose epimerase deficiency is an autosomal recessive disorder, [5] which means the defective gene is located on an autosome, and two copies of the defective gene - one from each parent - are required to inherit the disorder.
Symptoms that have not been associated with Duarte galactosemia, [23] and many individuals with Duarte galactosemia, do not need to restrict their diet at all. However, research corroborates a previously overlooked theory that Duarte galactosemia may lead to language developmental issues in children with no clinical symptoms.
The treatment for galactosemic cataract is no different from general galactosemia treatment. In fact, galactosemic cataract is one of the few symptoms that is actually reversible. Infants should be immediately removed from a galactose diet when symptoms present, and the cataract should disappear and visibility should return to normal. [12]
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 ...
This type of is associated with cataracts, but does not cause growth failure, mental retardation, or hepatic disease. Dietary reduction of galactose is also the treatment but not as severe as in patients with classical galactosemia. This deficiency can be systemic or limited to red blood cells and leukocytes.

Duarte galactosemia is an inherited condition associated with diminished ability to metabolize galactose due to a partial deficiency of the enzyme galactose-1-phosphate uridylyltransferase. [1] DG differs from classic galactosemia in that patients with Duarte galactosemia have partial GALT deficiency whereas patients with classic galactosemia ...
Unlike classic galactosemia, which is caused by a deficiency of galactose-1-phosphate uridyltransferase, galactokinase deficiency does not present with severe manifestations in early infancy. Its major clinical symptom is the development of cataracts during the first weeks or months of life, as a result of the accumulation, in the lens, of ...
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.
