Study Notes
Patient Symptoms
- Exhibits recurrent respiratory tract infections, sinusitis, pancreatitis, and salty sweat.
- Symptoms align with cystic fibrosis (CF) diagnosis.
Genetic Findings
- Genetic testing identifies a G551D mutation in one CFTR gene allele.
- Typically, CF is diagnosed when both CFTR alleles are mutated.
Diagnosis Challenge
- Only one CFTR mutation detected, despite the presence of classical CF symptoms.
- This indicates the possibility of an undetected second mutation.
Testing Limitations
- The testing utilized a 36-mutation panel, which may not cover all possible CFTR mutations.
- The absence of a second identified mutation suggests it could be outside the tested panel.
Conclusion
- The patient's clinical presentation and the presence of a single G551D mutation raise the likelihood of another unidentified CFTR mutation contributing to the condition.
