Summary
Familial polyposis coli and Peutz-Jeghers syndrome, rare genetic disorders, are reported for the first time in Ethiopia. These cases highlight new mutations and inherited transmission, emphasizing the need for early detection and management.
Area of Science:
- Genetics
- Gastroenterology
- Oncology
Background:
- Familial polyposis coli (FPC) and Peutz-Jeghers syndrome (PJS) are rare inherited gastrointestinal polyposis syndromes.
- These conditions significantly increase the risk of colorectal cancer and other malignancies.
Observation:
- This study reports the first documented cases of FPC and PJS in Ethiopia.
- One FPC case presented as a potential new gene mutation, while another case was possibly inherited.
- The FPC patient transmitted the condition to their offspring.
Findings:
- Genetic defects associated with FPC and PJS were identified in the Ethiopian population.
- Evidence of both de novo mutation and autosomal dominant inheritance patterns were observed.
- The affected FPC patient underwent total colectomy for cancer prophylaxis.
Implications:
- These findings establish the presence of FPC and PJS in Ethiopia, expanding the known geographic distribution of these diseases.
- Early diagnosis and genetic counseling are crucial for affected families in the region.
- Prophylactic surgery, like total colectomy, remains a vital strategy for preventing cancer in high-risk individuals.
