Stable isotope dilution analysis of N-acetylaspartic acid in CSF, blood, urine and amniotic fluid: accurate postnatal diagnosis and the potential for prenatal diagnosis of Canavan disease.

abstract：:Untreated pregnancies and their outcomes were studied in 10 women with histidinaemia and their 26 pregnancies. The mean maternal assigned histidine level was 727+/-186 micromol/L (range 484-1,053). Six women had classic histidinaemia (assigned level >700 micromol/L) and the remaining four had mild (atypical) histidina...
