cancer genetics assistant Interview Questions and Answers

1. What is the role of a cancer genetics assistant?

   • Answer: A cancer genetics assistant supports genetic counselors and other healthcare professionals in providing genetic services related to cancer risk assessment, testing, and counseling. Their duties often include collecting patient information, reviewing medical records, performing data entry, assisting with test ordering and result interpretation, and scheduling appointments.

2. Explain the difference between a germline and a somatic mutation.

   • Answer: Germline mutations are present in a person's DNA from conception and are found in every cell of the body. They can be passed down to future generations. Somatic mutations occur after conception in a single cell and are not inherited. They are only present in the cells descended from that original mutated cell.

3. What are some common cancer susceptibility genes?

   • Answer: BRCA1, BRCA2, TP53, PTEN, MLH1, MSH2, MSH6, PMS2, ATM, CHEK2, PALB2, CDH1 are some examples. The specific genes relevant depend on the type of cancer.

4. Describe the process of genetic testing for cancer risk.

   • Answer: It typically involves a referral from a physician, pre-test counseling, sample collection (blood or saliva), laboratory analysis, and post-test counseling to discuss the results and implications.

5. What are some ethical considerations in cancer genetics?

   • Answer: Maintaining patient confidentiality, ensuring informed consent, addressing potential psychological impact of test results, managing incidental findings, and navigating family implications are crucial ethical considerations.

6. What is a pedigree chart and how is it used in cancer genetics?

   • Answer: A pedigree chart is a visual representation of a family's medical history, showing the inheritance pattern of specific traits or diseases. In cancer genetics, it helps identify individuals at increased risk based on family history.

7. Explain the concept of penetrance and expressivity in cancer genetics.

   • Answer: Penetrance is the probability that a person with a particular genotype will exhibit the associated phenotype (e.g., develop cancer). Expressivity refers to the variability in phenotype among individuals with the same genotype (e.g., the severity or type of cancer).

8. What is Lynch syndrome?

   • Answer: Lynch syndrome (hereditary nonpolyposis colorectal cancer) is an inherited disorder that increases the risk of several types of cancer, including colorectal, endometrial, ovarian, and others, due to mutations in mismatch repair genes.

9. What is Li-Fraumeni syndrome?

   • Answer: Li-Fraumeni syndrome is a rare inherited disorder characterized by an increased risk of developing a wide range of cancers at an early age due to germline mutations in the TP53 tumor suppressor gene.

10. What is the role of genetic counseling in cancer risk assessment?

    • Answer: Genetic counselors assess family history, interpret genetic test results, discuss risks and benefits of testing, and provide support and guidance to individuals and families facing cancer risk.

11. What are some common challenges faced by cancer genetics assistants?
