Muller et. al. (Nucleic Acids Res.14:6489,1986) reported that DNA from these fibroblasts hybridized Y-chromosome-specific DNA probes mapping near to the putative testis determining locus. 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 XX male, was positive for the expected Y- and X-specific sequences. In addition, this XX male showed an extra PFGE fragment which was thought to represent a chromosomal polymorphism. Muller et al (Genomics 5:153-156,1989) investigated the Y-chromosomal DNA content of the DNA from this 46,XX male cell culture utilizing a number of Y-specific DNA probes. DNA from this culture hybridized some but not all of the probes. No hybridization was observed for probes Y-156, Y-190, and Y-223a which are specific for a proximal region of Yp containing a cluster of Y-specific moderately repeated DNA sequences. |
