What is G-6-PD?

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is inherited as an X-linked recessive disorder. This genetic condition was passed down in genes from one or both parents to their children and most often affects males. G6PD deficiency happens when the body doesn't have enough enzyme G6PD which helps to protect red blood cells (RBC) from damage and premature destruction. Without enough G6PD, the RBC break apart and this condition is called haemolysis. Red blood cells that don't have enough G6PD are sensitive to some medicines, foods, and infections. For instances, ingestion of certain types food (eg: fava beans) or exposure to certain types of chemicals (eg: naphthalene a chemical found in mothballs and moth crystals) may trigger acute haemolytic anemia.

Possible Inheritance Modes for G-6-PD

There is one inheritance mode of G-6-PD. Inheritance mode is how a gene will be passed down from parent to offspring.

X Recessive

X-linked recessive disorders are also caused by mutations in genes on the X chromosome. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females.
