简要总结
The objective of this project is to build a collection of biological samples consisting of fibroblasts and primary keratinocytes from patients with orphan monogenic diseases and to use these cells in the customization of functional tests. The miniaturized tests we are setting up make it possible to distinguish patient cells from control cells. They can be used to test molecules or for the development of diagnostic tests.
As part of the research protocol, the investigating physicians will be able to perform a skin biopsy on their patient included in the study. APTEEUS will isolate fibroblasts and keratinocytes and ensure their preservation. As part of the project, it is planned to preserve the biological samples collected and to preserve the collection after the end of the study. Skin fibroblasts and keratinocytes that are isolated from the biopsy are cells that can be preserved and amplified. They are a material of choice for the functional study of many monogenic diseases.
This study will allow the adaptation of tools dedicated to the functional study of monogenic diseases in order to help in the research and development of new treatments for these diseases, but also to highlight and explain the inter-individual variability of symptoms and responses to treatments, and finally, to help in the development of diagnostic methods.
Patients with orphan monogenic diseases whose genetic defect has been confirmed and for whom the study of the disease can be performed on fibroblasts, keratinocytes or cells derived from them, may be included in the study. Subjects, after information and consent, will undergo a skin biopsy. The sample will be sent directly to the promoter company APTEEUS, which will carry out all in vitro developments. The fibroblasts and keratinocytes will be preserved and will constitute a collection of cells "orphan monogenic diseases". The samples can be reused for new research in the same field.

结局指标
主要结局
Measurement of the residual enzymatic activity on the isolated fibroblast and or keratinocytes using appropriate methodology.
时间窗: 6 months
The function of the impaired enzyme will be assessed by measuring in vitro the residual enzymatic activity using labeled substrate. Technologies used are based on mass spectrometry. Residual enzymatic activity will be expressed as a percentage of normal controls.
