Galactosemia is a rare genetic metabolic disorder, in which an individual (usually an infant) lacks the enzyme GALT, which breaks down the sugar galactose in the body. Since galactoseis produced by the breakdown of lactose (in milk) into glucose, this sugar rapidly accumulates in the body, and may result in damage to the kidneys, liver, eyes, and brain.

Galactosemia is a rare genetic disorder where the body is unable to properly break down a sugar called galactose, which is found in dairy products and some fruits and vegetables. This can lead to a buildup of harmful substances in the body, causing symptoms such as liver damage, cataracts, and developmental delays if left untreated. Treatment involves avoiding foods that contain galactose.

Galactosemia is a rare inherited metabolic disorder in which a person cannot metabolize galactose, a sugar found in milk and other dairy products. This can lead to a build-up of galactose in the blood and urine and can damage the liver, kidneys, and brain. People with galactosemia need to avoid foods that contain galactose and may need to take supplements of glucose or other sugars.

Galactosemia is a rare, hereditary disorder of carbohydrate metabolism that affects the body's ability to convert galactose (a sugar contained in milk, including human mother's milk) to glucose (a different type of sugar).

The variant Duarte galactosemia, a much milder form of galactosemia, also involves a mutation in the GALT gene. Whereas classic galactosemia completely prevents the normal processing of galactose, the Duarte variant only reduces enzyme activity by ~75%, but not by 100% as in classic galactosemia. Children with Duarte galactosemia usually do not have serious health effects and may or may not need treatment.

Other types of classic galactosemia, far rarer, that are not discussed here include:

Galactosemia type II, caused by results from mutations in the GALK1 gene

Galactosemia type III, caused by mutations in the GALE gene

Can you grow out of galactosemia?

Galactosemia is a lifelong condition that children will not outgrow. However, galactosemia can be easily managed by following a galactose-free diet. ... The majority of fruits, vegetables, grains, breads, fats, and sugars are safe to eat as long as they contain little or no galactose. Oct 10, 2019

Classic galactosemia. Other Names: Galactose-1-phosphate uridyltransferase deficiency; Galactosemia type 1; GALT deficiency; Galactose-1-phosphate uridyltranferase deficiency; Galactose-1-phosphate uridyl transferase deficiency; Galactose-1-phosphate uridyl-transferase deficiency disease; Galactosemia, classic. Orpha Number: 79239

Definition. A life-threatening metabolic disease with onset in the neonatal period. Infants usually develop feeding difficulties, lethargy, and severe liver disease. Epidemiology: Global prevalence is unknown but estimated annual incidence has been reported to be between 1/40,000 and 1/60,000 in Western countries. The disorder appears to be more common in the Caucasian population than in other ethnic groups but figures in other populations may be underestimated. Males and females are equally affected. Clinical description: When ingesting breast milk or lactose-containing formula, infants develop feeding problems, failure to thrive, and signs of liver damage (jaundice, bleeding tendency, hypoglycemia). In the absence of appropriate treatment (galactose restriction), sepsis (E-coli) and neonatal death may occur. Despite adequate treatment, long-term complications appear including cognitive impairments, motor deficits, Etiology: Classic galactosemia is caused by mutations in the GALT (9p13) gene encoding the galactose-1-phosphate uridyltransferase enzyme. Mutations that severely impair enzyme activity result in the classic galactosemia phenotype. The so-called variants are mutations associated with higher residual enzyme activity resulting in milder or no features of galactosemia such as the Duarte variant (GALT gene mutation). Diagnostic methods In many countries, infants are routinely screened for galactosemia at birth. When neonatal screening is not performed, diagnosis is based on the clinical picture. Diagnosis can be confirmed by assay of the relevant metabolites, enzyme activity and GALT gene mutational analysis. Differential diagnosis. Differential diagnoses include galactose epimerase deficiency and other diseases causing acute liver disease in the neonate. Antenatal diagnosis testing is usually performed by sampling. In at-risk relatives, testing is also possible to search for the mutation when already identified in a family. Genetic counseling Galactosemia follows an autosomal recessive pattern of inheritance. Management and treatment. Treatment is based primarily on galactose restriction in the diet. Infants should be fed with soy formula or other lactose-free formula. Patients are advised to follow a lifelong diet. To prevent a diminished bone mass, calcium, vitamin D and vitamin K supplements are recommended if dietary intake does not meet the recommended daily allowance. Monitoring of cognitive and motor development, gonadal function and bone mass is mandatory. Eye examinations are recommended in case of neonatal cataracts or in case of poor dietary compliance. Despite dietary treatment long-term complications occur. Prognosis. Prognosis is dependent on age of diagnosis, disease severity and compliance with dietary restrictions, which affects the onset and course of secondary complications.

a "variant" of classic galactosemia called Duarte variant galactosemia, in which a person has mutations in the GALT gene but has only partial deficiency of the enzyme. Infants with this form may have jaundice, which resolves when switched to a low-galactose formula. Some studies have found that people with this form are at increased risk for mild neurodevelopmental problems, but other studies have found there is no increased risk. The risk may depend on the extent of the deficiency.

What can be treated by placing the affected individual on a restricted diet that excludes dairy products huntington disorder down syndromefaulty-enamel trait or galactosemia?

Galactosemia... the word "lactose" in this word should have given you a thoughtless answer.


What causes Galactosemia?

Galactosemia is a very rare disease that is received through a recessive trait. It is hardly diagnosed but can also be very easily confused with lactose intolerance. Though the two can be very similar but they are very different. Galactosemia is when your body cannot process galactose and lactose intolerance is when your body cannot process lactose. Lactose and galactose can be found in generally the same food group, dairy. The very important difference between the two is that lactose intolerance causes the symptoms of gas, cramps and diarrhea and galactosemia causes excess fat to build up in the brain, cause mental retardation and finally death.


What is the probability that the next two children will both be affected with galactosemia?

The probability that a child is affected with galactosemia is 1/40,000. The probability that both children are affected would be (1/40,000) * (1/40,000) = 1/1,600,000,000.


Do both parents have to be a carrier of galactosemia for the child to be a carrier?

No, if one parent is a carrier of galactosemia and the other parent is not, the child has a 50% chance of being a carrier as well. It only requires one parent to pass on the gene for the child to be a carrier.


What do galactosemia and tay-sachs disease have in common?

Both galactosemia and Tay-Sachs disease are genetic disorders caused by the absence or dysfunction of a particular enzyme. Galactosemia is a disorder where the body is unable to break down galactose, a sugar found in milk, while Tay-Sachs disease is a disorder where the body lacks an enzyme needed to break down certain lipids in the brain. Both conditions can lead to serious health complications if not managed properly.

The lack of which enzyme causes galactosemia?

The lack of the enzyme galactose-1-phosphate uridyltransferase (GALT) causes galactosemia. This enzyme is responsible for the breakdown of galactose in the body, and its deficiency leads to the accumulation of galactose and its toxic byproducts.
