The case of a sexchromatin negative “girl” with multiple malformations is presented. A small metacentric chromosome was found to replace her second X chromosome, half of which was strongly fluorescing after staining with Quinacrinedihydrochloride, and late replicating after labelling with tritiated thymidine. The chromosome was interpreted as a translocation chromosome between the long arms of a Y and a partially trisomic autosome.
