| Pathology (details) | Alport Syndrome (AS) is an inherited disease characterized by the association of a glomerular nephropathy, a sensorineural deafness, and retinal or corneal defects. Its frequency is about 1/5000. It is associated with mutations in one of the three genes encoding the alpha 3, 4, and 5 chains of type IV collagen, which form a distinct network in the glomerular basement membrane essential for the long-term stability of the glomerular filtration barrier. The disease can be inherited as a dominant X-linked, autosomal recessive, or autosomal dominant trait. Patients initially present with hematuria, followed by proteinuria and progressive renal failure. The median age at end-stage renal failure is about 20, but there is a large inter- and intra-familial variability. The progression of the disease can be divided into 4 stages: isolated hematuria, microalbuminuria, macroproteinuria, and progressive renal failure. Ear and ocular defects also exhibit progressive evolution. |

| Additional information regarding sample selection. |
Paediatric and adult patients will be mainly recruited through the network of reference competence and recognised expert centres of rare kidney diseases. Investigators will inform patients meeting the inclusion criteria about the RaDiCo-EURBIO-Alport cohort and invite them to participate during regular care follow-up visit for prevalent patient and during their first regular care visit (postdiagnosis) for incident patient.
