Glucose-6-Phosphate Dehydrogenase deficiency
Transcript of Glucose-6-Phosphate Dehydrogenase deficiency
Again, Males are more likely
Females on the other hand have two X chromosomes would need two mutated X chromosomes to be passed down for it to take effect. This gene contains genetic information for the G6PD enzyme to be produced. More than 140 mutations that cause this condition have been identified in the gene. Almost all these mutations lead to changes in amino acids that build the G6PD enzyme Red Blood cell Function So basically... When your body does not have enough of the G6PD enzyme the processes of altering glucose into another essential carbohydrate (such as ATP) for energy cannot occur as often or quickly Many with this disorder suffer from chronic exhaustion, someone with G6PD are usually unable to preform in activities that involved quick increases in heart rate. This can propose many problems in a child development... *Physically
Socially Development Physically Someone with G6PD will be limited to many kinds of foods and certain triggers that may cause problems in the body Certain types of materials can cause outbreaks such as mothballs, antibiotics, antipyretics, and naphthalene products Emotional G6PD deficiency can cause many emotion problems, such as: *Knowing it will be passed on to your child
*Inability to preform in a lot of sports
*Watching very closely on the foods you eat
*Accepting the genetic disorder An estimated 400 million people worldwide have G6PD deficiency. This condition occurs most frequently in certain parts of Africa, Asia, and the Mediterranean. It affects about 1 in 10 African-American males in the US What are the symptoms? When G6PD brings anemia some symptoms include:
Yellowing of the skin Yellowing of eyes
Shortness of breath Rapid heart rate G6PD deficiency is tested by taking a blood sample of the umbilical cord Without this enzyme or having few of them is like building a puzzle with a missing piece The gene is the blueprint for the G6PD enzyme! A day in the life Researchers believe that carriers may be partially protected against malaria. A reduction in the amount of functional glucose-6-dehydrogenase appears to make it difficult for a parasite to invade Dean Holder - G6PD Deficiency Trigger- Lemonade Couldn't stay awake How keeping it a secret effected Dean One of many... Is there a cure? "No, there is no known cure nor do you grow out of it. It is a life long condition. The only thing you can do is avoid substances which cause oxidative stress and that use G6PD. Carbohydrates require G6PD for the body to change them into energy for example. Legumes (especially the Fava Bean) contain the proteins vicine, convicine and isouramil which cause hemolysis" -G6pddefiency.org This pathway is almost like dominoes Treatment "The following medicines can sometimes cause problems for people with G6PD deficiency and should be avoided if possible
1) For infections avoid:
Nalidixic acid, Nitrofurantoin, Sulphonamides and Dapsone
3) Avoid close contact with:
Moth balls (Naphthaline)
4) Avoid eating:
Fava (Broad) beans and Chinese herbal medicines [and foods that cause hemolysis]
In most cases, cases of G6PD deficiency go undiagnosed until a child develops symptoms. If doctors suspect G6PD deficiency, blood tests usually are done to confirm the diagnosis and to rule out other possible causes of the anemia. If you feel that your child may be at risk due to your family history or your ethnic background, talk to your doctor about performing a screening with blood tests to check for G6PD deficiency is advisable.
With the right precautions, a child with G6PD deficiency can lead a healthy and active life" -AGIHlab.com/G6PD Blue- Discussed in class
