G6PD deficiency is a genetic disorder that most often affects males. Testing for G6PD deficiency is more accurate if done after the crisis, not while the infant is symptomatic. Most people with G6PD deficiency usually don't experience any symptoms. However, some may develop symptoms when they're exposed to the medication, food, or infection that triggers the early destruction of red blood cells. Once the underlying cause is treated or resolved, symptoms of G6PD deficiency usually disappear within a few weeks. The jaundice may be quite severe and, if untreated, may result in kernicterus. 4 Glucose 6-phosphate dehydrogenase (G6PD) deficiency is the most important disease of hexose monophosphate pathway.
