6PGD deficiency is a recessive hereditary disorder located on the P arm of chromosome 1. It is an autosomal disease, not associated with the sex chromosomes and can affect both sexes. The lack of synthesis of a specific protein on chromosome 1 has reduced a subject suffering from 6PGD deficiency from producing adequate amounts of the 6 ...
[2] [3] Prokaryotic and eukaryotic 6PGD are proteins of about 470 amino acids whose sequences are highly conserved. [4] The protein is a homodimer in which the monomers act independently: [ 3 ] each contains a large, mainly alpha-helical domain and a smaller beta-alpha-beta domain, containing a mixed parallel and anti-parallel 6-stranded beta ...
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, the effect is usually short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD ...
This enzyme is responsible for the interconversion of mannose-6-phosphate and mannose-1-phosphate, and its deficiency leads to a shortage in GDP-mannose and dolichol (Dol)-mannose (Man), two donors required for the synthesis of the lipid-linked oligosaccharide precursor of N-linked glycosylation.

NADPH deficiency can cause a dysfunction in glutathione peroxidase which is an enzyme that converts hydrogen peroxide (a reactive oxygen species) into water. G6PD ( glucose-6-phosphate dehydrogenase ) deficiency exacerbated by administration of oxidant drugs (e.g., primaquine , dapsone , quinidine ) can also result in Heinz bodies.
G6PD Deficiency is a genetic disorder and no more a disease than blond hair or brown eyes. You can not "catch" it from another person other than through conception. The article is well done and better than most I've seen. I received a letter from a Dr in India recently who believes G6PDD to be much more common than currently thought.
More than 40 severe class I mutations involve mutations near the structural site, thus affecting the long term stability of these enzymes in the body, ultimately resulting in G6PD deficiency. [13] For example, two severe class I mutations, G488S and G488V, drastically increase the dissociation constant between NADP + and the structural site by ...
