First trimester prenatal diagnosis of adrenoleukodystrophy by determination of very long chain fatty acid levels and by linkage analysis to a DNA probe

摘要

A first trimester prenatal diagnosis of adrenoleukodystrophy has been done on chorionic villi biopsy in the pregnancy of a carrier woman. Two different approaches allowed one to determine that the male fetus was affected: the linkage analysis of DNA from chorionic villi using the highly polymorphic probe St 14 and the determination of very long chain fatty acid levels in cultured chorionic villi.
