Hereditary Stomatocytosis - Variants

Variants

Haematologists have identified a number of variants. These can be classified as below.

• Overhydrated hereditary stomatocytosis
• Dehydrated HSt (hereditary xerocytosis; hereditary hyperphosphatidylcholine haemolytic anaemia)
• Dehydrated with perinatal ascites
• Cryohydrocytosis
• 'Blackburn' variant.
• Familial pseudohyperkalaemia

There are other families that do not fall neatly into any of these classifications.

Stomatocytosis is also found as a hereditary disease in Alaskan malamute and miniature schnauzer dogs.
