| Summary: | Introduction. Pompe disease is an autosomal recessive lysosomal storage disorder with marked morbidity and mortality, if untreated. With the advent of enzyme replacement therapy, it is essential to identify the infantile-type as early as possible to mitigate the effects of the enzyme deficiency. Identification is possible prenatally with testing of both parents. More recently, many states have instituted newborn screening for this condition. Case. We report a patient with infantile-onset Pompe disease with a normal paternal carrier genetic test, born prior to newborn screening for Pompe disease in the state of Michigan. The infant's father was retested once the infant was diagnosed with Pompe disease postnatally and noted to have a mutation conducive to Pompe disease. Conclusion. Providers should have a strong clinical suspicion for disorders even if prenatal parental carrier screening is normal. A normal parental prenatal test does not exclude the possibility that the fetus may be diagnosed with a disorder postnatally, and pediatricians may be faced with limitations in accuracy of parents' recollection of parental testing results. |
