Abstract/OtherAbstract:
Propionic acidemia is a frequent inborn error of metabolism. Methylcitric acid, a key indicator of propionic acidemia, increases in the amniotic fluid of affected fetuses. For prenatal diagnosis, the methylcitric acid in amniotic fluid can be measured by stable-isotope dilution GC/MS. Here, we quantified this indicator in samples of amniotic fluid that had been dried on filter paper and transported at ambient temperatures, and compared the results with data obtained from the original amniotic fluid. We then used the filter-paper method to screen at-risk fetuses and obtained a clear-cut diagnosis in each case.
