Brief Summary
Hereditary stomatocytosis is a heterogeneous group of rare constitutional diseases of dominant transmission in the vast majority of cases. The data concerning their clinical and biological presentation, and their evolution are few, and come from about thirty clinical cases. The constitution of an exhaustive French cohort of hereditary stomatocytosis will improve the establishment of the diagnosis and the management of patients
