Marylee’s son, father, and two cousins have BCM. Like most affected families, the correct diagnosis wasn’t made until 2017 when her son was diagnosed by molecular genetic testing. Marylee is an alum of UNC-Chapel Hill and Jefferson Medical College and competed residency at Baylor College of Medicine. After four years in private practice as a dual-boarded internist and pediatrician, she now works at a private equity firm in New York City.
