This enzyme is involved in the process of oxidative phosphorylation and is vital for maintaining NADPH levels, which are necessary for protecting cells from oxidative stress. Patients with G6PD deficiency have increased sensitivity to various factors, including some medications, infectious diseases and certain foods, which can lead to hemolysis of red blood cells and clinical manifestations such as anemia, jaundice and fatigue. The disease has a polyetiological nature and can manifest itself in varying degrees of severity, which makes it an important topic for medical research and practice.<\/p>\n<div id=\"ez-toc-container\"

The most interesting historical fact is that in the 1970s, the genetic nature of this disorder was established, opening up new horizons for understanding inherited metabolic disorders. It is also known that G6PD deficiency is more common in people of African descent and in people of Mediterranean origin, making this disorder an interesting object of study in the context of evolutionary biology.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Glucose-6-phosphate dehydrogenase deficiency has different prevalence rates in different populations.
