XY female with a dysgerminoma and no mutation in the coding sequence of the SRY gene

We report a 46,XY 11-year-old girl with pure gonadal dysgenesis who developed a dysgerminoma. The testis-determining gene SRY, a candidate for sex reversal, whose alterations seem to correlate with dysgerminoma, was analyzed and found to be normal; its coding sequence was negative for deletions and mutations. DMRT-1 gene mapping on 9p and DAX-1 on Xp21 were also normal. These results suggest the involvement of other genes in sex reversal and call into question the putative relationship between SRY alterations and dysgerminoma.
