A family demonstrating short arm deletion of the X chromosome as a consequence of X-16 balanced translocation in the mother is reported. The two Xp- sisters exhibit clinical signs of gonadal dysgenesis, while the balanced carriers are phenotypically normal. To our knowledge this represents the only example of both the balanced carrier state for an X translocation and its genetic consequence occurring in the offspring, as well as the involvement of X-16 interchange. Literature data of 37 additional cases of verified X translocations are discussed.
