title: Abnormal motor behaviour and developmental postmortem findings in a fetus with Fanconi anaemia.
abstract: Prenatal diagnosis in the third pregnancy of a mother who already had one healthy son and one son with Fanconi anaemia (FA), revealed that her fetus was also affected with FA. At 22 weeks a maternal complaint about excessive fetal kicking starting at 15 weeks, focused our attention on the behaviour of the fetus, which was observed by means of real-time ultrasound for 30 min. The differentiation of specific movement patterns was strongly diminished. The qualitative expression of general movements was considered to be consistently abnormal due to the fact that they were performed with large amplitudes, high speed and abrupt onsets. The incidence of general movements was within the normal range, however, the distribution in the burst-pause pattern was abnormal. Postmortem examination showed a spongy myelinopathy of the central nervous system that may account for the abnormal motor activity. This combination of findings has not been previously reported in association with FA.
