| abstractText | Mus musculus domesticus Y chromosomes (Y-DOM Chrs) vary in their ability to induce testes in the strain C57BL/6J. In severe cases, XY females develop (XY(DOM) sex reversal). To identify the molecular basis for the sex reversal, a 2.7-kb region of Sry, the testis-determining gene, was sequenced from Y-DOM Chrs linked to normal testis determination, transient sex reversal, and severe sex reversal. Four mutations were identified. However, no correlation exists between these mutations and severity of XY(DOM) sex reversal. RT-PCR identified Sry transcripts in XY(DOM) sex-reversed fetal gonads at 11 d.p.c., the age when Sry is hypothesized to function. In addition, no correlation exists between XY(DOM) sex reversal and copy numbers of pSx1, a Y-repetitive sequence whose deletion is linked to XY sex reversal. We conclude that SRY protein variants, blockade of Sry transcription, and deletion of pSx1 sequences are not the underlying causes of XY(DOM) sex reversal. (C) 1996 Academic Press, Inc. |
