Final answer:
Decay acceleration factor (CD55) deficiency was not detailed in the references, but the related topic of G6PD deficiency was discussed. It is a common enzyme deficiency that leads to the premature breakdown of red blood cells and the potential development of anemia.
Step-by-step explanation:
Decay acceleration factor (CD55) deficiency is not mentioned directly in the reference information provided. However, in relation to enzyme deficiencies, the material discusses glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is a genetic disorder characterized by low levels of G6PD. This enzyme is crucial in the pentose phosphate pathway, which maintains the reducing energy in cells by ensuring a supply of NADPH. NADPH, in turn, preserves glutathione levels that protect red blood cells from oxidative damage. G6PD deficiency is a common enzyme deficiency and can lead to the premature breakdown of red blood cells and result in conditions such as anemia.
The aforementioned pyruvate dehydrogenase complex deficiency (PDCD) and phenylketonuria (PKU) are also genetic enzyme disorders. PDCD involves a deficiency in the enzyme that converts pyruvate into acetyl-CoA, impeding the Krebs cycle and ATP production, which can lead to a range of severe neurodegenerative symptoms. Treatments for such enzyme deficiencies include diet modification, vitamin supplementation, and in some cases gene therapy.
