There is also a salt-losing form (a more complete 21-hydroxylase deficiency), a hypertensive form (11-hydroxylase deficiency), a 17-hydroxylase deficiency form, a desmolase deficiency form, and a 3-beta-hydroxysteroid deficiency form.

Type II is the most common of the 3 types of congenital dyserythropoietic anaemia; it is often referred to as hempas, based on the hereditary erythroblast multinuclearity with positive acidified serum test. (12 Dec 1998) |
| anaemia, haemolytic, congenital | Haemolytic anaemia due to various intrinsic defects of the erythrocyte. (12 Dec 1998) |
| anaemia, haemolytic, congenital nonspherocytic | Any one of a group of congenital haemolytic anaemias in which there is no abnormal haemoglobin or spherocytosis and in which there is a defect of glycolysis in the erythrocyte.
