Long Read Sequencing Rare Genetic Diseases Neurodevelopmental Diseases Diagnostic

ClinConnect Summary

Ten families with a child suffering from a neurodevelopmental disease will be recruited by geneticists being part of the CLAD-Ouest. An EDTA blood sample will be taken from the patient and their parents (trio analysis). The blood samples will then be used to extract nucleic acids (DNA).

The blood samples will be sent and centralized to the genetics laboratory of the Nantes University Hospital. The DNA will be extracted and anonymized.

The files generated after DNA sequencing will have as an identification key the anonymization number provided at the time of inclusion of the individual in ...
