| GENE MAPPING & DOSAGE STUDIES - Y CHROMOSOME |
Nishioka and Lamothe (Am J Med Genet 27:711-717,1987) reported that DNA from this 46,XX male cell line failed to hybridize to a 3.4 kb Y chromosome repetitive sequence DNA probe (LA26). |
| |
| TESTIS DETERMINING LOCUS |
Muller et. al. (Nucleic Acids Res.14:6489,1986) reported that DNA from these fibroblasts did not hybridize 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 sexdetermining locus on the Y chromosome (ZFY). This culture, from an XX male, did not have any of the Y-specific fragments detectable using conventional or pulsed-field gel electrophoresis. |

| Remarks |
Phenotypically male; G6PD type B; Xg(a) antigen pos; DNA from fibros does not hybridize Y-chromosome-specific DNA probes mapping near to the putative testis determining locus; gene dosage studies consistent with 2 copies of STS |
