a problem

Greetings folks. I need your help. This couple has had 6 miscarriages, a TA for congenital abnormalities, and a normally developing 4 year old daughter. Her 1st 3 pregnancies miscarried all at @ 5 weeks. No studies that I'm aware of on the PoCs. She then had a sperm washed conception, and that's her daughter. The next pregnancy was the aborted fetus, normal chromosomes, 46,XY. Prenatal US suggested anophthalmia, slight enlargement of the cerebral ventricles with anterior communication between the lateral ventricles consistent with holoprosencephaly. Follup autopsy could only document the anophthalmia. The suggestion is that this is autosomal recessive, a not uncommon Lebanese disorder. Following this she has once more miscarried 3 times. The first was +16, the second was 46,XX, and the third (last month) was +22. Chromosome studies on mom and dad were normal, although I'm having them reviewed for quality of the preparation. The family history is clear of any congenital abnormilities or consanguinity or repeated miscarriages. Does anyone have a scenario that can wrap this into a single cause? Many thanks. Allen.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
