ICD10 code of Lowe Syndrome and ICD9 code

Lowe syndrome, also known as oculocerebrorenal syndrome, is classified under ICD-10 code E72.03 for Lowe syndrome and ICD-9 code 270.8 for other specified disorders of amino-acid metabolism. These diagnostic codes are essential for medical billing, clinical documentation, and identifying the condition within health records for patients navigating this rare, X-linked genetic disorder.

What is the clinical significance of Lowe syndrome?

Lowe syndrome is a rare multisystem disorder that primarily affects the eyes, the central nervous system, and the kidneys. Because it is an X-linked recessive condition, it almost exclusively affects males. The syndrome is caused by mutations in the OCRL gene, which encodes an enzyme involved in the processing of phosphoinositides, critical components of cell membranes. Individuals with Lowe syndrome often experience congenital cataracts, intellectual disability, and renal tubular dysfunction, specifically Fanconi-type proximal renal tubular acidosis.

How is Lowe syndrome diagnosed and coded?

Diagnosis of Lowe syndrome is typically confirmed through a combination of clinical evaluation and genetic testing. Clinicians use ICD-10 code E72.03 to specifically document the condition, ensuring that specialists and insurance providers recognize the complexity of the patient's care needs. While ICD-9 code 270.8 is largely historical, it remains relevant for reviewing older medical records. Early identification is vital to manage the progressive nature of the disease, particularly the kidney complications that require specialized metabolic monitoring.

What are the primary symptoms associated with Lowe syndrome?

Managing the health of a patient with Lowe syndrome requires a multidisciplinary approach due to the wide range of systems involved. Physicians must track several core clinical features to provide comprehensive care:

• Ocular: Bilateral congenital cataracts are present at birth in nearly 100% of cases, often accompanied by glaucoma.


• Renal: Proximal renal tubular dysfunction (Fanconi syndrome) leads to the loss of bicarbonate, amino acids, and phosphate in the urine.


• Neurological: Hypotonia (low muscle tone) is commonly observed in infancy, often followed by delayed motor development and varying degrees of intellectual impairment.


• Skeletal: Many patients develop osteomalacia or rickets due to the chronic loss of phosphate and calcium through the kidneys.


• Behavioral: Some individuals may exhibit challenging behaviors, including irritability or obsessive-compulsive tendencies.

Is Lowe syndrome hereditary?

Lowe syndrome is inherited in an X-linked recessive pattern. This means the OCRL gene mutation is located on the X chromosome. Because males have only one X chromosome, a single mutated copy is sufficient to cause the condition. Females are typically carriers who do not exhibit symptoms, though they carry a 50% risk of passing the mutation to their sons. Genetic counseling is strongly recommended for families affected by Lowe syndrome to understand the recurrence risks and available reproductive options.

Next steps

• Consult a pediatric nephrologist and an ophthalmologist to coordinate the specialized care required for Lowe syndrome.


• Engage with a clinical geneticist to verify the OCRL mutation and discuss family screening.


• Connect with the 1 member currently registered on DiseaseMaps.org to share experiences and find community support.


• Monitor renal function through regular blood and urine analysis to manage metabolic imbalances effectively.
