Influences on Female Adolescents' Decisions Regarding Testing for Carrier Status of XSCID
The purpose of this study is to learn what factors influence adolescent girls' decisions regarding testing for carrier status of X-Linked Severe Combined Immunodeficiency (XSCID). It will provide information about how healthy relatives feel about whether they could be XSCID carriers, whether carrier testing should be pursued, and, if so, at what age. Commonly known as "Bubble Boy Disease," XSCID is a rare, life-threatening immune system disorder that affects only males, but females who carry the gene mutation can pass the disease to their male children.
Adolescent girls 13 to 17 years old who have a relative with XSCID and are known to be at risk for being carriers are eligible for this study.
Participants will receive genetic counseling to help them decide if they want to be tested for the XSCID gene. Those who elect to be tested will provide a DNA sample from either a blood draw or brushing taken from inside the mouth. They will receive the test results from the same genetic counselor they spoke with before the testing.
All participants will also talk with a psychologist over the phone once a year for 3 years to answer questions about how they are feeling and what they know about XSCID. They will be asked to discuss their decision and feelings about carrier testing.
