A sex chromosome deletion was identified in the course of prenatal diagnosis for maternal age. Ultrasound pictures revealed male fetal sex and a comparison with the father's Y chromosome suggested that the altered chromosome might be a de novo deletion of the Y chromosome. DNA hybridization with five human Y-specific probes shows that, among the Y-specific sequences recognized by the probes, only two of them are absent. The normal infant, at birth, was mosaic 46, XYq-/46,XY.
