Question
Based off the information given, complete the table a. What mode of inheritance pattern best fits this pedigree in your opinion?
You are a second-year medical student in an innovative medical school that allows you to get in-depth clinical
experience early in your medical education. You are currently assigned to work with Dr. Aikenhed, a pediatric
oncologist. She has done a biopsy on a tumor-like growth in the adrenal gland of her 17-year-old male patient, Lee F.
You record the following notes while Dr. Aikenhed takes a detailed family history from the patient's parents:
• Lee has a sister, Leah (age 10), and a brother, Luke (age 6). Both are healthy.
• Lee's mother, Grace, was diagnosed with bilateral breast cancer last year at age 35. Lee's father, Brian, and Lee's
paternal grandparents have no history of cancer.
•
Grace is the youngest of four children. Her eldest brother, Greg (age 42), and sister, Greta (age 40), have never had
any signs or symptoms of cancer. She had a brother, Geoff, who died of leukemia at age 8. He was the third child
of Grace's parents.
Greg's two fraternal twin daughters have no signs or symptoms of cancer.
Grace's father, Roger, died of a soft tissue sarcoma at age 35. Grace's mother, Renee, is still living and in excellent
health.
Roger's mother died of a brain tumor at age 30. Roger was her only child.
