Methods
Charts from children and young adults with melanocytic lesions who were seen by Genetic Predisposition Clinic (GPC) at St. Jude Children’s Research Hospital (SJCRH) between June 2014 and September 2021 and underwent germline testing were retrospectively evaluated. Demographic, clinical, family history, and germline genetic test results were gathered. Results of cascade testing from first degree relatives were reviewed if available. This study was approved by the Institutional Review Board at SJCRH.
