What this trial studies

This observational study explores a cohort of pediatric and adolescent patients diagnosed with 46, XY Disorders of Sex Development (DSD) across multiple centers in Italy. It aims to collect and analyze clinical, biochemical, instrumental, and genetic data to better understand the phenotypic, hormonal, and genetic characteristics of these patients. The study will also assess the correlation between molecular diagnoses and external masculinization scores, as well as evaluate the diagnostic rate over the reporting period. The research is coordinated by the IRCCS Azienda Ospedaliero-Universitaria of Bologna.

Who should consider this trial

Good fit: Ideal candidates for this study are pediatric and adolescent patients diagnosed with 46, XY DSD who are under 18 years of age.

Not a fit: Patients with a karyotype other than 46, XY DSD will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding and management of 46, XY DSD, leading to improved patient outcomes.

How similar studies have performed: While there have been studies on DSD, this multicenter approach focusing on a large cohort is relatively novel.
