OBJECTIVE: To investigate the phenotype, pathogenesis and molecular biological features of 46, XX testicular disorder of sex development.
METHODS: We obtained the history of 2 patients with 46, XX testicular disorder of sex development, examined the cavitas pelvis by type-B ultrasonography, analyzed the karyotype of the chromosome, and detected the genes SRY, YRRM1, DYS240 and DAZ by PCR amplification.
RESULTS: Microrchidia, azoospermia and maldevelopment of secondary sex characteristics were observed in both of the patients, but ultrasonography revealed no female internal genitals. Their chromosome gender was karyotyped as 46, XX, with the SRY gene positive in both, but the YRRM1 gene positive in only one of the cases.
CONCLUSION: Chromosome karyotyping and detection of the SRY gene for patients with abnormal sex development can give us an insight into the genetic pathogenesis and provide us with scientific evidence for the diagnosis and treatment of the condition.
