Abstract

OBJECTIVE:

To investigate the presence of mutations in the open reading frame (ORF), as well as on the 5' and 3', flanking regions of the SRY gene in patients with mixed gonadal dysgenesis (MGD) or with Turner syndrome (TS) and Y mosaicism.

STUDY DESIGN:

We studied 13 patients with MGD and three patients with TS and Y mosaicism. DNA was isolated from blood leukocytes for subsequent polymerase chain reaction (PCR) and direct sequencing were performed in the ORF, as well as from the 5' and 3' flanking regions of the SRY gene.

RESULTS:

No mutations were present in any of the patients studied.

CONCLUSION:

The absence of mutations in these regions indicated that mutations were an unlikely cause of MGD or TS with Y mosaicism and suggested that there are others genes playing an important role in sex development.
