Summary
A 28-year-old man, whose infant son died of multiple malformations, was shown to have a balanced 13q-/18q+ translocation. He was phenotypically and mentally normal. Studies of the pedigree revealed the presence of bilateral microtia on the side of the spouse of the proband, transmitted in a dominant mode through four generations. Occasional cells from the proband and his mother exhibited an elongated long arm of a chromosome 16.
