Exclusion of late infantile neuronal ceroid lipofuscinosis (LINCL) in a fetus by assay of tripeptidyl peptidase I in chorionic villi.
We report the exclusion of late infantile neuronal ceroid lipofuscinosis in a fetus by assay of tripeptidyl peptidase I activity and by mutational analysis in chorionic villi. This is the first pregnancy at risk for LINCL to be monitored by enzyme assay. No morphological abnormalities were detected.
