    Abstract:
    Hereditary spherocytosis (HS) is a very heterogenous condition both at clinical and biochemical level. To establish the relationship between these aspects we performed a clinical and biochemical study in 87 Italian HS subjects. Patients were divided into three groups based on clinical severity (mild, typical and severe) and into five subgroups based on specific membrane abnormalities identified by polyacrylamide gel electrophoresis (isolated spectrin deficiency, spectrin deficiency combined with mild ankyrin reduction, spectrin deficiency combined with severe ankyrin reduction, band 3 reduction and isolated protein 4.2 reduction). We were not able to assess any alteration in six HS patients. A good correlation between clinical HS forms and membrane protein defects is shown. We conclude that erythrocyte membrane analysis should be carried out after diagnosis of HS in order to predict the clinical course of the disease.
