It has been demonstrated that a blood protein deficiency is the cause of this inherited illness.
Protein deficiency is common in children (43% of children five years of age or less) resulting not only in a high mortality rate but irreversible mental retardation and restricted body development in survivors.
The best vitamin E form for preventing or reversing this deficiency is the liquid form: tocopheryl polyethylene glycol 1000 succinate (TPGS), because the body absorbs it more readily.
Although my asymmetric hearing deficiency is most likely a congenital problem — that was nevertheless almost undetectable until my early 20s — the doctor wants to do one more test to rule out a benign tumor.
Folic acid deficiency is a leading cause of spina bifida and other neural tube defects in newborns, and can be prevented by taking folic acid supplementation during pregnancy.
Quite likely the single biggest piece of good news about G6PD deficiency is that it is widely understood to confer protection against malaria, in particular the most deadly form of that disease.

The five diseases studied by the CLiC team are: Alagille Syndrome (AGS), Alpha-1-antitrypsin deficiency (a-1AT), Bile acid synthesis and metabolism defects, Mitochondrial hepatopathies, and Progressive familial intrahepatic cholestasis (PFIC).
(This deficiency is not completely protective against drinking, however, particularly if there is social pressure and high exposure to alcohol, such as among college fraternity members.) * Some people with alcoholism may have an inherited dysfunction in the transmission of serotonin.
