Genetic Risk Factors and Testing

Understanding Genetic Risk Factors for Breast Cancer

Introduction: Kate and Jane's Situation

• Kate, in her mid-30s, has been diagnosed with breast cancer.
• Jane, in her early 30s, learns she has a 50% chance of inheriting an allele that increases her risk.
• Jane is concerned about her risk and wants to know more about the pathogenic variant involved.

Key Questions Raised

• How is a gene associated with a disease identified?
• How can we determine if a specific sequence variant within a known disease gene is pathogenic?
• When can genetic testing be used to determine our risk, and what are its limitations?

Significance and Implications:

• These questions are important areas of ongoing research.
• They have significant implications for understanding how our genomes affect our health.
