Study Stresses Importance of Early Treatment for Different Mutations

A better understanding of Pompe disease-causing genetic mutations may help with early treatment intervention, even if symptoms are subtle, a small Hungarian study suggests. Researchers found that the precise localization of a mutation determines the impact on GAA enzyme activity, which in turn has been associated with disease onset.

How Can an Enzyme Activity Test Help Diagnose Pompe Disease?

One test that doctors use to diagnose Pompe disease, a rare genetic disease caused by mutations in the GAA gene, is an enzyme activity test. GAA provides cells with the instructions necessary to make an enzyme that plays a role in breaking down a complex sugar molecule called…

Screening Programs May Identify Newborns at Risk for Late-onset Pompe Disease, Other Lysosomal Storage Disorders

Newborn screening for lysosomal storage disorders, including Pompe disease, is much more likely to detect individuals at risk for late-onset disease, according to a four-fear analysis of data from a pilot newborn screening program. The study “The New York pilot newborn screening program for lysosomal storage diseases: Report of the…
