Title: Investigation of SRY Gene in Sex Reversed Syndrome Patients
Abstract: SRY (sex-determining region Y chromosome) is considered as a strong candidate for the TDF (testis determining factor) and has been cloned following another candidate ZFY (zinc finger protein gone). In this study,eight cases of sex reversal, including four 46, XX males and four 46, XY females were examined for the presence of SRY sequence and a Y-repeated DNA locus. Our data indicated that the genomie DNA of the four classical 46,XX males had the SRY sequences. On the other hand, both SRY sequences and Y-repeated DNA sequences were present in aii four 46, XY females.These results suggest that SRY sequences were responsible for the sex reversal of 46, XX males whereas there may be other genetic mechanisms for the sex reversal of 46, XY females without the lack of SRY sequences.
