Testicular disorder of sex development in the presence of a 46,XX karyotype is a rare condition. In most instances, it is caused by an X;Y translocation in the paternal gametes, causing SRY to be transferred on the X chromosome. An abnormal recombination event between homologous genes PRKX and PRKY is implicated in approximately one third of the cases. In this study, we report the characterization by fluorescence in situ hybridization of four patients with a 46,X,der(X)t(X;Y) constitution: two monozygotic adult twins, one adult male and a young boy. Molecular cytogenetic analyses using BAC clones specific to the X and Y chromosomes revealed that the translocation is not mediated by an abnormal PRKX-PRKY recombination event in any of our patients. On the other hand, the twins and the adult male have similar breakpoints, having almost the entire short arm of the Y chromosome translocated on their der(X). On their der(X) chromosome, breakpoints are located close to PRKX, in an interval of less than 200 kb. As for the young boy, his breakpoints are located approximately 300 kb proximal to SRY, in Yp11.31, and at the beginning of the pseudoautosomal region in Xp22.33. Our data suggest that some regions are prone to breakage on the sex chromosomes and that these regions represent possible hot spots for X;Y translocations that are not mediated by abnormal recombination.
