What is the most severe type of galactosemia?

Classic galactosemia, also known as type I, is the most common and most severe form of the condition. If infants with classic galactosemia are not treated promptly with a low-galactose diet, life-threatening complications appear within a few days after birth.

What is galactosemia type 2?

Galactokinase deficiency or galactosemia type II is a rare inborn error of galactose metabolism. Galactosemia type II is rarer and more insidious than other galactosemia types and results in the formation of nuclear cataracts without provoking intolerance symptoms.

What is the normal range for galactosemia?

In classic galactosemia Normal level of erythrocyte galactose-1-phosphate is <1 mg/dL. Plasma free galactose is usually >10 mg/dL, but may be as high as 90-360 mg/dL (5-20 mmol/L). Galactose-1-phosphate uridylyltranserase (GALT) enzyme activity is absent or barely detectable.

Is galactosemia recessive or dominant?

Galactosemia is an autosomal recessive genetic disorder. Recessive genetic disorders occur when an individual inherits a non-working gene from each parent.

Can a baby with galactosemia breastfeed?

There is no cure for classic galactosemia; instead, children are treated with a special galactose-free diet in which they avoid all milk and milk-containing products as much as possible for the rest of their lives. This includes: Breastmilk.

Is there a cure for galactosemia?

The most common treatment for galactosemia is a low-galactose diet. This means that milk and other foods that contain lactose or galactose can’t be consumed. There is no cure for galactosemia or approved medication to replace the enzymes.

Which is more common type 1 or Type 2 galactosemia?

Type 1 galactosemia occurs in 1 out of every 30,000 to 60,000 babies. Type 2 galactosemia is less common than type 1 and occurs in 1 out of every 100,000 babies. Type 3 and Duarte variant galactosemia are very rare. Galactosemia is more common among those who have Irish ancestry and among people of African descent living in the Americas.

What happens to a baby with galactosemia type II?

Babies with type II or type III also will have fewer issues than babies with classic galactosemia. However, they still can develop cataracts, kidney and liver issues, and have delayed growth. Girls with galactosemia may require hormone treatment when they reach puberty.

What happens if you have too much galactose in your blood?

Galactosemia means having too much galactose in the blood. The buildup of galactose can lead to serious complications and health problems. There are four main types of galactosemia disorders: type 1, or classic and clinical variant galactosemia. type 2, or galactokinase deficiency.

What happens if there is no diagnosis of galactosemia?

Multiple complications can appear if galactosemia isn’t diagnosed and treated right away. The buildup of galactose in the blood can be dangerous. Without diagnosis and intervention, galactosemia can be life-threatening in newborns. Common complications of galactosemia include: Premature ovarian insufficiency is only seen in women.

What are the statistics on too much galactose?

Statistics on Galactosemia. 1. Type II Galactosemia has the same issues as classic Galactosemia, but only results in cataract formation when too much galactose is in the body. 2. Galactosemia is not the same as lactose intolerance. It is far more serious. 3. If left untreated, classic Galactosemia will kill 3 out of 4 infants.

How is galactosemia the same as lactose intolerance?
