Summary
Hereditary prostate cancer (PCa) susceptibility involves complex genetics. While some high-risk genes exist, most familial risk likely stems from multiple moderate-risk genetic variants, requiring further research.
Area of Science:
- Genetics
- Epidemiology
- Oncology
Background:
- Decades of research confirm a genetic component in prostate cancer (PCa) susceptibility.
- Evidence suggests a significant, yet heterogeneous, hereditary influence on PCa risk.
Purpose of the Study:
- To review genetic epidemiological research in hereditary prostate cancer.
- To discuss mapping efforts and challenges in understanding PCa genetic etiology.
Main Methods:
- Review of epidemiological studies on hereditary prostate cancer.
- Analysis of genetic mapping efforts and gene identification in PCa susceptibility loci.
Main Results:
- Initial studies suggested Mendelian inheritance due to high-risk loci.
- Identification of several PCa susceptibility loci, with genes cloned at three loci.
- Current evidence favors a model of multiple moderate-risk genetic variants contributing to familial PCa risk.
Conclusions:
- While specific genes have been identified, their overall contribution to hereditary and sporadic PCa is likely modest.
- The inheritance of multiple moderate-risk genetic variants is the leading hypothesis for excess familial PCa risk.
- Further research is needed to address unanswered questions in hereditary prostate cancer genetics.
