Next generation sequencing (NGS) allows some better diagnostic results, particularly, in the rare diseases field. At a twenty five percent rate, those exams highlight some variants which are not yet described in human pathology. The relationship between a variant found inside a candidate gene and a pathology, is able to be confirmed by functional studies at a protein level. This study aims to build a biological collection to feed further functional studies to confirm the relationship between NGS identified variants, and the clinical signs and symptoms.

Primary outcome measure(s)
Identification of at least 80 new genes implicated in rare diseases via high-throughput sequencing technics and through functional studies. — 23 years Candidate genes, suspected to be responsible for rare diseases will be identified before the inclusion, during standard medical care, by exome or genome sequencing.
Collecting biological samples to build up a biobank — 23 years After a candidat gene identification, patient will be proposed sampling (blood or urine) or if a skin biopsy, an amniotic fluid puncture or any surgery are done during standard care, the remaing tissue or fluid, or operative wastes will be eligible too, to be stored in the biobank.
Candidat gene validation through functional studies. — 23 years Biological samples from the biobank will be made available after the study, to some specialized research teams, in order to validate or overturn those previously gene candidates by the way of some biological technics.
