According to the Pompe Registry, diagnostic delays in Pompe disease are common and the median time to diagnosis from sign/symptom onset in late-onset Pompe disease has been observed to be up to 12.6 years.9
Pompe disease can be diagnosed by performing an acid α-glucosidase (GAA) enzyme activity assay resulting in deficient enzyme activity and confirmed by a genetic test resulting in 2 pathogenic GAA variants.4
New to molecular testing?
This short video provides general education on molecular testing for healthcare providers who are unfamiliar with the process.
In 2015, the US Newborn Screening Advisory Committee recommended, and the Secretary of US Department of Health and Human Services accepted the recommendation, to add Pompe disease to the Recommended Uniform Screening Panel (RUSP)10
- The Recommended Uniform Screening Panel (RUSP) is a list of disorders recommended by the Secretary of the Department of Health and Human Services (HHS) for states to screen as part of their state universal newborn screening (NBS) programs.
