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

Outcome Measures

Primary Outcomes (1)

  • Obtain a description of the clinical and laboratory data of patients at the time of diagnosis of stomatocytosis

    Descriptive analysis of clinical and biological data for the diagnosis of stomatocytosis

    Baseline

Secondary Outcomes (4)

  • Determine the proportion of recurrent genetic mutations and private mutations within our cohort

    Baseline

  • Establish phenotypes-genotypes relationships

    through study completion, an average of 15years

  • Describe the appearance of complications

    through study completion, an average of 15years

  • Describe possible new phenotypic presentations of hereditary stomatocytosis

    through study completion, an average of 15years
