MPS IV (Morquio syndrome)


What causes this disease?

Children with MPS IV are missing an enzyme which is essential in cutting up the mucopolysaccharides called keratan sulfate. The incompletely broken down mucopolysaccharides remain stored in cells in the body causing progressive damage. Babies may show little sign of the disease, but as more and more cells become damaged, symptoms start to appear.

How common is MPS IV?

MPS IV is one of the rarest of the MPS diseases in the United States. Reliable incidence figures are not available, but estimates have varied between 1 in 200,000 live births to 1 in 300,000 live births.

How is the disease inherited?

MPS IV is caused by a recessive gene. The only way is if two individuals carrying the gene reproduce and then the offspring has a ¼ chance of being born with it.

Is there a cure for MPS IV?

There is no cure, but research in treatments is promising.
