An account is given of a family identified by a newborn malformed male. The chromosome anomalies described are interpreted as indicating that the father has a balanced translocation with a reciprocal exchange between no. 9 and no. 12. The supernumerary chromosome resembling a group F element, which is found in the propositus, is in fact one of the two rearranged chromosomes present in the father. The propositus therefore is trisomic for part of no. 9 and no. 12. His brother has a normal karyotype. Possible meiotic situations leading to the formation of the observed karyotypes are discussed.
