Genes affected

H6PD (HGNC:4795): (hexose-6-phosphate dehydrogenase/glucose 1-dehydrogenase) There are 2 forms of glucose-6-phosphate dehydrogenase. G form is X-linked and H form, encoded by this gene, is autosomally linked. This H form shows activity with other hexose-6-phosphates, especially galactose-6-phosphate, whereas the G form is specific for glucose-6-phosphate. Both forms are present in most tissues, but H form is not found in red cells. [provided by RefSeq, Jul 2008]

H6PD Gene-Disease associations (from GenCC):

• cortisone reductase deficiency 1

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics
