Regarding G6PD deficiency true are ?
**Core Concept**
G6PD deficiency is a genetic disorder that affects the enzyme glucose-6-phosphate dehydrogenase (G6PD), which is crucial for maintaining the integrity of red blood cells. This deficiency leads to an increased susceptibility to oxidative stress, resulting in hemolysis.
**Why the Correct Answer is Right**
G6PD is responsible for protecting red blood cells from oxidative damage by maintaining the levels of reduced glutathione. When G6PD is deficient, red blood cells are more prone to hemolysis, especially in response to triggers such as fava beans, certain medications (e.g., primaquine, sulfonamides), and infections. The enzyme is found in red blood cells, where it helps to counteract oxidative stress caused by reactive oxygen species.
**Why Each Wrong Option is Incorrect**
**Option A:** This option may be incorrect if it does not accurately describe the pathophysiology of G6PD deficiency.
**Option B:** This option may be incorrect if it does not account for the role of oxidative stress in hemolysis.
**Option C:** This option may be incorrect if it does not acknowledge the genetic basis of G6PD deficiency.
**Clinical Pearl / High-Yield Fact**
A classic exam trap is to confuse G6PD deficiency with other causes of hemolytic anemia, such as autoimmune hemolytic anemia or paroxysmal nocturnal hemoglobinuria (PNH). It's essential to remember that G6PD deficiency is a genetic disorder that can be triggered by specific oxidative stressors.
**Correct Answer:** C. This option should accurately describe the genetic basis of G6PD deficiency and its association with oxidative stress.
