Renal Fanconi syndrome is diagnosed by its cardinal features of glycosuria without diabetes, aminoaciduria, phosphaturia, and renal tubular acidosis. It is often associated with hypokalaemia, hypophosphatemia and rickets. We report a seven-year-old boy with nephropathic cystinosis who presented with all the cardinal features of renal Fanconi syndrome associated with rickets, pathological fractures, stage IV chronic kidney disease (CKD) and hypothyroidism. Slit-lamp examination of the cornea confirmed the diagnosis. However glycosuria was conspicuously absent. Whenever there are features of rickets with failure to thrive and recurrent vomiting renal rickets should be ruled out. Cystinosis is one such disorder and we report this case due its rarity and interesting clinical presentation.

The renal tubule and collecting duct express a large number of proteins, all having putative immunoreactive motives. Therefore, all can be the target of pathogenic autoantibodies. However, autoimmune tubulopathies seem to be rare and we hypothesize that they are underdiagnosed.

Tenofovir-associated Fanconi syndrome (TAFS) is a proximal renal tubule disorder rarely reported in patients after liver transplantation (LT) for hepatitis B (HBV). In a retrospective review of 79 HBV-LT recipients, 8/66 (12.1%) on tenofovir post-LT developed TAFS.

Aims: Light chain proximal tubulopathy (LCPT) is a rare complication of paraprotein-related diseases. We report a case series to present the clinicopathological characteristics and outcomes of LCPT.
Methods: A multicentre retrospective case series of 47 patients with LCPT, consisting of 36 crystalline, three non-crystalline, and eight mixed LCPTs, was studied between January 2007 and December 2023.
