A sex-linked recessive disorder affecting multiple systems including the EYE, the NERVOUS SYSTEM, and the KIDNEY. Clinical features include congenital CATARACT; MENTAL RETARDATION; and renal tubular dysfunction (FANCONI SYNDROME; RENAL TUBULAR ACIDOSIS; X-LINKED HYPOPHOSPHATEMIA or vitamin-D-resistant rickets) and SCOLIOSIS. This condition is due to a deficiency of phosphatidylinositol 4,5-bisphosphate-5-phosphatase leading to defects in PHOSPHATIDYLINOSITOL metabolism and INOSITOL signaling pathway.

An X-linked inherited multisystem metabolic disorder caused by mutations in the OCRL1 gene. The main manifestations of this disorder result from involvement of the eyes, nervous system and kidneys. Signs and symptoms include congenital cataracts, infantile glaucoma, intellectual disability, hypotonia, aminoaciduria and renal tubular dysfunction.

An X-linked, multisystem, metabolic disorder caused by mutations in the OCRL1 gene, the primary manifestations of which result from involvement of the eyes, nervous system and kidneys, and include congenital cataracts, infantile glaucoma, intellectual disability, hypotonia, aminoaciduria, and renal tubular dysfunction.

Lowe syndrome (oculocerebrorenal syndrome) is characterized by involvement of the eyes, central nervous system, and kidneys. Dense congenital cataracts are found in all affected boys and infantile glaucoma in approximately 50%. All boys have impaired vision; corrected acuity is rarely better than 20/100. Generalized hypotonia is noted at birth and is of central (brain) origin. Deep tendon reflexes are usually absent. Hypotonia may slowly improve with age, but normal motor tone and strength are never achieved. Motor milestones are delayed. Almost all affected males have some degree of intellectual disability; 10%-25% function in the low-normal or borderline range, approximately 25% in the mild-to-moderate range, and 50%-65% in the severe-to-profound range of intellectual disability. Affected males have varying degrees of proximal renal tubular dysfunction of the Fanconi type, including low molecular-weight (LMW) proteinuria, aminoaciduria, bicarbonate wasting and renal tubular acidosis, phosphaturia with hypophosphatemia and renal rickets, hypercalciuria, sodium and potassium wasting, and polyuria. The features of symptomatic Fanconi syndrome do not usually become manifest until after the first few months of life, except for LMW proteinuria. Glomerulosclerosis associated with chronic tubular injury usually results in slowly progressive chronic renal failure and end-stage renal disease between the second and fourth decades of life.

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 (OCRS) is an X-linked recessive metabolic disorder described by Lowe and coworkers in 1952. It is a multisystem disorder that primarily affects the eyes, nervous system, and kidneys.

Lowe oculocerebrorenal syndrome is a rare condition that primarily affects the eyes, central nervous system and kidneys. Some of the signs and symptoms associated with the condition are often present from birth, including congenital cataracts and other eye abnormalities; hypotonia (reduced muscle tone); and feeding difficulties.
