Trans-counseling: A case series of transgender individuals at high risk for BRCA1 pathogenic variants
Abstract
Transgender individuals comprise a growing patient population in genetic counseling practice. The identification of a pathogenic variant in a cancer susceptibility gene may impact a transgender person's decisions regarding hormonal and/or surgical transition. Limited scientific literature exists on specific genetic counseling needs and medical management strategies for transgender individuals. In addition, most genetic counselors have had limited experience and training in conducting genetic counseling sessions with transgender patients. In this report, we describe three cases of transgender individuals who underwent genetic counseling and testing in our clinic. All were at ≥50% risk to carry a familial BRCA1 pathogenic variant. Case 1 is a 20-year-old transgender female initiating hormonal agents. Case 2 is a 19-year-old transgender male considering surgical decisions who has a BRCA1 pathogenic variant on both sides of the family. Case 3 is a 24-year-old transgender male who had previously undergone gender-affirming mastectomy (top surgery) and is taking androgen therapy. Unique aspects of genetic testing, psychosocial counseling, and medical management of transgender individuals have arisen in the course of their care. In this report, we discuss our experiences and practices of case preparation, case management, appropriate genetic testing, and medical management such as screening, surgical decisions, and coordination of care. There is a need for more research in this area…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
