The deoxyribonucleic acid from nine subjects with a 45,X/46,XY karyotype with a cytogenetically intact Y chromosome and phenotypically presenting with bilateral streak gonads, streak and testis, or bilateral scrotal testes along with a control male and female were analyzed for the presence of the zinc finger Y sequence through the molecular probe pDP1007. This particular probe is thought to constitute part of the putative testicular-determining factor gene. All the study subjects demonstrated the presence of zinc finger Y. Laser densitometry studies confirmed a correlation between the intensity of the zinc finger Y band and the percentage of Y cell lines. This study supports the fact that individuals with mixed gonadal dysgenesis and cytogenetically intact Y chromosomes will tend to have intact zinc finger Y sequences.
