2 Glucose-6-phosphate dehydrogenase( g6pd ) Deficiency is the most commonhuman enzyme Deficiency ; it affects anestimated 400 million people Deficiency is also known as favism, since g6pd deficient individu-als are also allergic to fava Deficiency is a genetic conditionthat is inherited in an X-linked recessivefashion. This means that males are morelikely to be affected by this condition thanare females. Genetic testing is available toidentify a Deficiency in g6pd in bothmales and is very important to tell any doctor orother health professional (such as nurse orpharmacist) that you have g6pd Defi-ciency to avoid a possible harmful reactionto treatments they might happens if you have g6pd Deficiency ?

3 Hemolytic anemia and prolonged neonataljaundice are the two major problems asso-ciated with g6pd Deficiency . Both of theseproblems are directly related to the inabilityof specific cell types to regenerate a mol-ecule called nicotinamide adenine dinucle-otide phosphate in its reduced form(NADPH); this reaction is normally cata-lyzed by the g6pd enzyme. Aside fromneonatal jaundice, hemolytic anemia canonly arise when a person with g6pd Defi-ciency is exposed to certain chemicals; oth-erwise, they live a normal anemia is the decreased abil-ity of red blood cells to transport oxygenthroughout the body; consequently, if youare having a hemolytic crisis, you will prob-ably feel tired and out of breath, and mayhave a dark colored urine.

4 Certain oxida-tive drugs, infections, or fava beans (and thepollen from the fava bean plant) can causethis. When any one of these agents entersthe red blood cell, hemoglobin becomes de-natured, thus destroying its function as theprinciple oxygen carrying normal cells, NADPH would play arole in removing these harmful oxidantsfrom the cell. Among the drugs contra-in-dicated for g6pd deficient individuals areaspirin and most anti-malarial drugs; for-tunately, g6pd deficient individuals are re-sistant to malarial infection. Treatments forhemolytic anemia include nasal oxygen,bed rest, human haptoglobin products,folic acid, and blood jaundice (a yellowing of themucous membranes and other body tissuesat birth) is a common condition in all new-borns, but when it persists, g6pd defi-ciency is suspected.

5 The newborn becomesjaundiced as a result of decreased activityof g6pd in the liver. This can be a poten-tially serious problem as it can cause severeneurological complications.
