Trisomy 20p from maternal translocation and anencephaly. Case report and genetic review

Ann Genet. 1989;32(4):247-9.


This paper concerns the case of an anencephalus male fetus with partial trisomy 20p product of a maternal translocation 46,XX, t(15;20) (p11.2;p12), ascertained by prenatal diagnosis. A cytogenetic review of previous cases is presented. Several hypotheses are discussed in order to explain the recurrent abortions of the mother and the aetiology of anencephaly in this last pregnancy.
