Limb body wall complex and amniotic band sequence in sibs.

We report on a woman who gave birth consecutively to an infant with limb body wall complex (LBWC) and then to an infant with amniotic band sequence (ABS). This paper reviews the different etiological hypotheses and the classification problems for the amniotic band diseases. No maternal factors were found, but this clinical report suggests further research in this direction, as well as the need to look more closely at the relation between LBWC and ABS.
