Cyclopia as a result of an unbalanced familial translocation, rcp(7;18)(q34;q21)

Abstract

One fetus is described with cyclopia and associated abnormalities as a result of an unbalanced translocation involving chromosomes 7 and 18 [46XX,del 7, rcp(7;18)(q34;21)]. The parents had had a previous infant described as having possible holoprosencephaly, but no medical records were available to substantiate this description.
