Galactosemia :: essays research papers

ga milk sugarmiaGa milk sugarmia is a genetically inherited metabolic affection. This disorder leaves the disabled with a partial or complete lack of the enzyme Galactose 1 Phosphate Uridyl Transferase (GALT). This enzyme is found in the bloodstream and it is used for breakout down the sugar galactose. This disorder comes in two different variations. though there is more than one type, it is still rare, having only 1 in 80,000 origins being modify by the disorder. unspotted Galactosemia is the first and more honey oil give of the disorder. This is the form when the affected has a complete loss of the enzyme. both(prenominal) recruits must contribute a galactosemic gene for a child to suck this very deadly form of the disorder. Because the body has none of the enzyme needed to enlistment galactose into glucose an accumulation occurs that is like a poison and is highly fatal. Classic Galactosemia is treatable by dint of a stringent diet of absolutely no lactose or galac tose. Some common foods containing these are dairy products, legumes, breast milk, and numerous other foods. A test for galactosemia is done at the time of birth with other tests. If left untreated 75% of infants will die. Some make of having classical galactosemia include an enlarged liver, kidney failure, cataract, and brain damage.Duarte Galactosemia is the second form. This form is when there is only a partial loss of the enzyme. The activity is usually 25%-50% that of a normal child. A child can get this form of galactosemia by inheriting a classic galactosemia gene from one parent and a duarte gene from the other. Much like classic galactosemia, duarte is found through a test done soon after birth. A strict diet is not needed for this form of the disorder. Instead a diet, it is recommended that lactose be slowly introduced untill normal consumption is accepted by the body. Because the affected can still process the foods, just not as tumefy as a fully functional body.A pe rson with no galactosemia receives two normal genes for production of the GALT enzyme in the bloodstream. This persons genotype is N/N and they have normal fully functioning enzyme activity. A carrier of classic galactosemia inheriets one affected gene and one non, this persons genotype is G/N. This person has less than normal enzyme activity, but nothing that requires a diet or medical treatment. A classic galactosemic has two classic galactosemia genes.
