Verga and Erickson (Am J Hum Genet 44:756-765,1989) used pulsed-field gel electrophoresis (PFGE) to study the short arm of the Y chromosome by using a pseudoautosomal probe (MIC2Y) and adjacent Y-specific sequences 27a and 47z (DSXY5) in XX males and XY females. In addition, the authors utilized the probe pDP1007 which was cloned from the putative sex-determining locus on the Y chromosome (ZFY). This culture, from an XY female, had all the expected Y-specific sequences, especially the putative TDF clone. In addition, this XY female showed an extra PFGE fragment which was not seen for other XY females and was thought to represent a chromosomal polymorphism. |

| Remarks |
Pure gonadal dysgenesis; 46,XY; ? H-Y antigen; right gonadal tissue (GM03368); positive for TDF gene sequences (ZFY); a cell line from this same donor is also available from a left gonadal streak (GM03368A) |
