OBJECTIVE: To report recurrent transmissions of Barth syndrome through a single oocyte donor carrying a de novo TAZ mutation. DESIGN: Case report. SETTING: Clinical molecular diagnostics laboratory. PATIENT(S): Oocyte donor and individuals conceived with her oocytes. INTERVENTION(S): Molecular testing. MAIN OUTCOME MEASURE(S): Detection of TAZ mutation. RESULT(S): Multiple individuals affected with Barth syndrome conceived from a single oocyte donor who is a carrier of a de novo TAZ mutation. CONCLUSION(S): We report multiple transmissions of Barth syndrome through a single oocyte donor with a de novo TAZ mutation.
