cg part#1| Classic galactosemia (CG) is an autosomal recessive disorder of galactose metabolism that affects approximately 1/50,000 live births in the USA. Following exposure to milk, which contains large quantities of galactose, affected infants may become seriously ill. Early identification by newborn screening with immediate dietary galactose restriction minimizes or prevents the potentially lethal acute symptoms of CG. However, more than half of individuals with CG still experience long-term complications including cognitive disability, behavioral problems, and speech impairment. Anecdotal reports have also suggested frequent gastrointestinal (GI) problems, but this outcome has not been systematically addressed. In this study we explored the prevalence of GI symptoms among 183 children and adults with CG (cases) and 190 controls. Cases reported 4.5 times more frequent constipation (95% CI 1.8–11.5) and 4.2 times more frequent nausea (95% CI 1.2–15.5) than controls. Cases with genotypes predicting residual GALT activity reported less frequent constipation than cases without predicted GALT activity but this difference was not statistically significant. Because the rigor of dietary galactose restriction varies among individuals with galactosemia, we further tested whether GI symptoms associated with diet in infancy. Though constipation was almost four times as common among cases reporting a more restrictive diet in infancy, this difference was not statistically significant. These data confirm that certain GI symptoms are more common in classic galactosemia compared to controls and suggest that future studies should investigate associations with residual GALT activity and dietary galactose restriction in early life.

Classic galactosemia (CG) results from profound deficiency of galactose-1-phosphate uridylyltransferase (GALT) activity and affects approximately 1/50,000 live births in the USA (Pyhtila et al. 2015). Following exposure to milk, which contains large quantities of galactose, affected infants can become seriously ill and die if not immediately switched to a low-galactose formula (Berry 2014). Early identification by newborn screening and rapid dietary intervention generally prevents or resolves the potentially lethal acute symptoms of CG (Berry 2014).

What causes galactosemia II?
Galactosemia II is caused by defects in both copies of the gene that codes for an enzyme called galactokinase (GALK). The frequency of occurrence of galactosemia II is about one in 100,000-155,000 births.
Is Lactose intolerance dominant or recessive trait?
Lactose intolerance is typically considered a recessive trait. It is caused by a reduced ability to produce the enzyme lactase, which digest lactose. If an individual inherits two copies of the gene associated with lactose intolerance (one from each parent), they are likely to be lactose intolerant.
What disorder is worse and why autism or dyslexia?
This question is a bit biased; as many of those with high-functioning autism see it not as a curse, but a gift. But common brain disorders which would be considered more debilitating than autism include Alzheimer's disease, multiple sclerosis, Parkinson's disease and Huntington's chorea.
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 types of eating disorder's is theire. including galactocemia. Galactocemia is an eating disorder?
classic galactosemia. 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.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, ovarian dysfunction with reduced fertility in women and diminished bone density. Male fertility has not yet been thoroughly studied. 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 diagnosisPrenatal testing is usually performed via gene mutation analysis by chorionic villus 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. Parents of an affected child have a 25% chance of having affected children in subsequent pregnancies. Management and treatmentTreatment 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.
