Sex-linked recessive disorder of amino acid transport which affects the eye, nervous system, and kidney; manifestations include cataract, glaucoma, aminoaciduria, hypophosphatemic rickets, developmental delay, myopathy, peripheral neuropathy, and hypotonia; associated with deficient activity of the enzyme phosphatidylinositol 4,5-bisphosphate-5-phosphatase.

Oculocerebrorenal syndrome (also called Lowe syndrome) is a rare X-linked recessive disorder characterized by congenital cataracts, hypotonia, intellectual disability, proximal tubular acidosis, aminoaciduria and low-molecular-weight proteinuria. Lowe syndrome can be considered a cause of Fanconi syndrome (bicarbonaturia, renal tubular acidosis, potassium loss and sodium loss)..
