Galactosemia (British galactosaemia, from Greek γαλακτόζη + αίμα, meaning galactose + blood, accumulation of galactose in blood) is a rare genetic metabolic disorder that affects an individual's ability to metabolize the sugar galactose properly.
Classic galactosemia has an autosomal recessive pattern of inheritance. All forms of galactosemia are inherited in an autosomal recessive manner, meaning individuals affected with classic galactosemia must have inherited a mutated copy of the GALT gene from both parents. Each child from two carrier parents would have a 25% chance of being ...
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.
Duarte variant galactosemia, DG, or Biochemical variant galactosemia) Leloir metabolic pathway: Galactose-1Puridylyltransferase (GALT, red font) is the middle enzyme in the Leloir pathway of galactose metabolism.
Juvenile/adult subtype symptoms include impaired balance or coordination, dark red spots on the skin or angiokeratomas, vision loss, seizures, and muscle jerks or myoclonus. The symptoms of this subtype tend to be less severe than the first two subtypes, and typically start in adolescence, with the average age being 16 years of age.

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.
This could also cause a “marked lack of enthusiasm for daily tasks,” Porter says, adding that these symptoms “go beyond” normal fatigue. What is the connection between sleep and preventing ...
