Lowe Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Lowe Syndrome?
Lowe syndrome is usually managed by a team. A geneticist (a doctor who treats inherited conditions), a nephrologist (a kidney doctor), and an ophthalmologist (an eye doctor) often lead care. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Lowe syndrome?
Lowe syndrome is a rare condition that mainly affects the eyes, brain, and kidneys. It is also called oculocerebrorenal syndrome. It occurs almost exclusively in males.
Symptoms can range widely in type and severity, even among members of the same family.
Symptoms
Common signs include:
- Eyes: babies are born with thick clouding of the lenses in both eyes, called congenital cataracts. This can make it hard to see.
- Glaucoma, an eye disease with high pressure inside the eye, develops in about half of affected infants.
- Muscles: weak muscle tone from birth can cause feeding trouble, problems with breathing, and slow sitting, standing, and walking.
- Development: many people have delayed development, and intellectual ability ranges from normal to severely impaired. Behavior problems and seizures have also been reported.
- Kidneys: the kidneys cannot take important nutrients back into the blood, so the nutrients pass out in the urine. This can cause more urination, dehydration, and acid build-up in the blood.
Kidney problems get worse over time. In older children and adults, they can lead to life-threatening kidney failure.
Causes and who gets it
Changes in the OCRL gene cause Lowe syndrome. A gene is a set of instructions inside your cells.
Lowe syndrome is X-linked. This means the gene is on the X chromosome, one of the two sex chromosomes. Males have only one X chromosome, so one changed copy is enough to cause the condition.
In some cases, an affected boy inherits the change from a mother who carries one changed copy. Other cases are new changes in the gene in boys with no family history. For a female carrier, each pregnancy has a 25% chance of a son with the disease.
Women who carry one changed copy do not have the usual features of Lowe syndrome. Most have changes in the lens of the eye that a thorough eye exam can find. These changes typically do not affect vision.
How doctors diagnose it
Doctors usually diagnose Lowe syndrome in males with genetic testing plus the typical signs. Genetic testing looks for changes in the OCRL gene.
Doctors look for dense cataracts in both eyes at birth. They also look for a kidney problem that makes the kidneys lose important substances. Loss of small proteins in the urine is often the earliest and most sensitive sign of kidney problems.
Testing before birth is possible if the gene change is already known in an affected male relative or in the mother.
Treatment
No treatment that cures Lowe syndrome is available in routine care. Treatment is supportive, which means it manages problems as they come up.
- Eyes: cataracts need surgery to remove them, ideally in infancy. Many children then need special glasses or contact lenses.
- Glaucoma is often hard to treat with medicine and frequently needs surgery. Lifelong care by an ophthalmologist, an eye doctor, is needed.
- Kidneys: care aims to correct chemical imbalances and slow kidney disease. One common treatment is alkali therapy, which helps neutralize extra acid in the blood.
- If the kidneys fail, dialysis, a treatment that removes waste from the blood, becomes necessary. Kidney transplant has been used in a limited number of cases.
- Bones: bone disease is treated with vitamin D and phosphate supplements. Too much vitamin D can raise calcium in the urine and the risk of kidney stones, so doctors check blood levels.
- Muscles and brain: physical therapy starts early for low muscle tone. Seizures are managed one person at a time with seizure medicines.
Blood platelets, the cells that help blood clot, may not work well. Bleeding after surgery may return hours later. Doctors should know about this risk before any surgery.
When to see a doctor
See a doctor if a baby is born with clouded eyes, weak muscle tone, or feeding trouble. Tell every surgeon about the bleeding risk before any procedure. Follow your doctor's instructions about any medicines.
Call 911 or go to the emergency room for bleeding that will not stop, severe trouble breathing, or a seizure.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Such a doctor can do an evaluation, help coordinate eye, kidney, and genetic specialists, and follow growth and development between specialist visits.
Common questions
Is Lowe syndrome inherited?
Yes, Lowe syndrome is inherited in an X-linked pattern. Some cases come from a mother who carries one changed copy of the OCRL gene. Other cases are new changes in boys with no family history.
Can females have Lowe syndrome?
Yes, but very rarely. Lowe syndrome occurs almost exclusively in males. Female carriers usually do not have the full condition, but most have lens changes in the eye.
Can Lowe syndrome be cured?
No treatment that cures Lowe syndrome is available in routine care. Treatment is supportive and focuses on managing symptoms such as eye, kidney, and muscle problems.
Is Lowe syndrome serious?
Yes, it can be. Kidney problems get worse over time. Life expectancy is reduced, most often because of kidney disease or complications such as infections.
