One study reported that 22% of patients on tenofovir developed at least 2 out of 6 features of proximal tubular dysfunction such as hyperaminoaciduria, glycosuria in the presence of normoglycaemia, and hyperphosphaturia. (5) Tenofovir may also cause renal failure.
Hyperaminoaciduria and hyperphosphaturia occur as a result of 20HPT.

Hypophosphatemic rickets (HR) is a rare genetic disorder, which is characterised by diminished phosphate reabsorption in renal tubules leading to chronic hyperphosphaturia and hypophosphatemia, which are associated with normal or low levels of 1,25(OH)2 Vitamin D3.
