Unexplained polycythemias are rare diseases, and therefore, the collection of data inherent to these diseases will not only improve their characterisation, but also allow stratification according to the risks and the course of the disease. The objective of this project is to constitute a database on the disease which will allow us to better understand it and in due course improve its management. The GENRED project thus bears uniquely on the collection of information, which will be gathered throughout the usual management of patients for this type of disease.
Cohort
There is one SNP
The required tests are: complete blood counts - Blood electrolytes - Arterial and venous gazes - Serum erythropoietin dosage - Liver function tests - JAK2 mutations (both V617F and exon 12) - Bone marrow aspirate and/or biopsy and/or endogenous BFU-E culture - Abdominal ultrasound - Lung function tests Inclusion Criteria: The characteristics of the patients included in the database will be described in terms of numbers and percentages for qualitative variables and in terms of means and standard deviations or medians and interquartile intervals for quantitative variables. --- V617F ---
