OBJECTIVES METHODS
CONCLUSIONS
The study included 379 patients comprising a wide spectrum of
presenting features, associated with different arrays of
chromosomal abnormalities aiming at studying the prevalence of
Sex chromosomal abnormalities among DSD patients
Patients were subjected to detailed clinical
examination, pubertal staging, cytogenetic and FISH
analysis. Laparoscopy with gonadal biopsy and FISH
on gonadal tissue cells were done when indicated
• Sex chromosomal abnormalities constitute a high proportion of DSD
• Application of ACGH is necessary for diagnosing MCA with DSD
• Detection of Y abnormalities in MGD is necessary for genetic counseling and gonadectomy ( dysgerminoma)
