Brief Summary:
This study seeks to identify genetic causes of conditions that affect the gonads and genitals, and to study the impact on families of receiving genetic results.

Condition or disease Intervention/treatment Phase
Disorders of Sex Development Hypospadias Genetic: Return of Genetic Results Not Applicable

Detailed Description:
This study seeks to understand the genetic causes of conditions that affect the development of the genitals, such as differences of sex development (DSD) and hypospadias, and the impact on families of receiving genetic results. The investigators are recruiting individuals with DSD and/or hypospadias without a clear genetic cause along with their family members for our research study. The investigators will collect samples for genetic studies. The investigators will review the clinical record for history, labs and physical exam information. The investigators will also build a tissue bank of blood, urine, and discarded tissues from surgeries. The investigators will return results of genetic testing to parents/guardians of children with DSD/hypospadias and have them complete questionnaires to assess the impact of receiving these results.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Genetic Testing
Subjects will provide a DNA sample, which will be screened for variants in genes related to DSD/hypospadias. Probands/parents who wish to receive results of genetic testing related to DSD/hypospadias will receive these results directly from the research study. Parents who receive results of genetic testing for probands 17 years old or younger will complete questionnaires at the time of enrollment, right after receiving genetic results, and 3 months after receiving genetic results.
 Genetic: Return of Genetic Results
The results of testing for genetic causes of DSD/hypospadias will be returned to parents of subjects who elect to receive these results.
