You may be eligible if
Genetically proven Alport syndrome (AS) - defined as following:
* gt;Men having hemizygous pathogenic/likely pathogenic variants involving COL4A5 gene - classified as X-linked AS involving men
* gt;Women having heterozygous pathogenic/likely pathogenic variants involving COL4A5 gene - classified as X-linked AS involving women
* gt;Both men and women with heterozygous pathogenic/likely pathogenic variants involving COL4A3 or COL4A4 genes - classified as autosomal dominant AS
* gt;Both men and women with homozygous pathogenic/likely pathogenic variants involving COL4A3 or COL4A4 genes - classified as autosomal recessive AS
* gt;Patients having variants of uncertain significance will be included if the fulfill at least 2 of the following criteria: (1) clinical features suggestive of AS, (2) positive family history suggestive of AS (i.e., at least one grade I relative having the same variant and presenting clinical features suggestive of AS) and (3) kidney biopsy showing the characteristic lesion of AS (i.e., structural defect of the glomerular basement membrane, "basket-wave" appearance of the basement membrane, lamination of the basement membrane) or for thin basement membrane disease (i.e., diffusely thin basement membrane)
Age between 18 and 70 years-old at the time of enrolment
