Single centre, prospective pilot study examining the relevance to screen for Fabry disease in a cohort of patients who have undergone renal transplantation for nephropathy of indeterminate cause, vascular nephropathy, diabetic nephropathy or secondary focal segmental hyalinosis with no established cause.

Exploration whether Fabry disease cases can be identified among patients who are followed at the Montpellier University Hospital after renal transplantation, with indeterminate cause of renal failure or diabetic nephropathy (due to its high frequency) or secondary focal segmental hyalinosis (FSH).

At the population level, the identification of cases at the Montpellier centre could then justify to expand this screening to other French centres. The goal is to contribute to adapt current guidelines of renal failure assessment, by systematically including Fabry among the diagnostic tests. Whether all patients with renal failure are concerned, or only those with indeterminate cause, is an important question this study will address.

Inclusion Criteria:

• Nephropathy of indeterminate cause, or secondary FSH or diabetic nephropathy
• Patients with kidney transplanted
• Patients still followed at the Montpellier University Hospital
• Obtaining written informed consent
• Age > 18 years old, no upper age limit

Exclusion Criteria:

• N/A

Patients identified from a database, who have undergone renal transplantation for nephropathy of indeterminate cause, vascular nephropathy, diabetic nephropathy or secondary focal segmental hyalinosis with no established cause, and still followed at the Montpellier University Hospital.
