Wagr Syndrome: Causes, Symptoms, and Treatment

What kind of doctor treats Wagr Syndrome?

A primary care doctor usually coordinates care, with specialists often involved, including a geneticist, an eye doctor, a nephrologist, an oncologist, and developmental specialists. 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 it is

WAGR syndrome is a rare condition that a person is born with. The name stands for four problems that often happen together: Wilms tumor, a kidney cancer of young children; aniridia, meaning part of the colored ring of the eye is missing; genitourinary differences; and developmental delays. Not everyone has all of these problems.

Symptoms

Signs differ from person to person. Many babies are born with aniridia, which can cause light sensitivity and blurry vision. The most serious kidney risk is Wilms tumor, which usually appears before age five. Genitourinary differences may affect the urinary tract or reproductive organs. Many children have delays in sitting, walking, or talking, and some have seizures.

Causes and who gets it

A piece of chromosome 11 is missing, including several neighboring genes. One gene, PAX6, affects eye development; another, WT1, affects the kidneys. In most cases the missing piece is a new change and neither parent has it.

How doctors diagnose it

Doctors often suspect WAGR syndrome when a baby is born with aniridia along with other findings. A chromosomal microarray, a blood test, can confirm it. Kidney imaging and regular urine tests check kidney health.

Treatment

There is no cure; treatment focuses on each person's specific problems. Children with aniridia see eye doctors regularly. Because of the Wilms tumor risk, most children get kidney ultrasounds about every three months until about age 7 or 8. Speech and physical therapy address developmental delays.

When to see a doctor

Talk to a doctor if a child is born with a missing or partly missing iris, has repeated urinary or kidney problems, or is slow to sit, walk, or talk. Any child with WAGR syndrome needs regular kidney screening. Sudden belly pain, blood in the urine, or a belly lump needs urgent care.

How a direct primary care or concierge doctor fits in

A direct primary care doctor is paid a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can spend extra time coordinating care, ordering kidney screening, and referring to specialists.

Common questions

Is WAGR syndrome inherited from parents?

Usually not. In most cases the missing piece of chromosome 11 is a new change that happened around the time the child was conceived. A geneticist can test family members if there are questions.

Will every child with WAGR syndrome get Wilms tumor?

Not every child does, but the risk is high enough that regular kidney ultrasounds are standard until about age 7 or 8. Early finding of the tumor usually improves the outlook, though results differ from child to child.

Can people with WAGR syndrome live independently as adults?

It depends on the person. Some people have mild learning delays while others need lifelong support. Long-term follow-up with doctors is recommended because kidney disease can appear later in life.

Can WAGR syndrome be prevented?

No. It is a genetic change that happens before birth, and there is no known way to prevent it. Prenatal testing can sometimes find it during pregnancy.
