Chronic granulomatous disease secondary to a rare compound heterozygote mutation in an adolescent cured by hematopoietic stem cell transplantation: a case report
To report a case of chronic granulomatous disease (CGD) in an adolescent and the successful treatment following hematopoietic stem cell transplantation, highlighting the role of advanced genetic sequencing techniques.
Approach:
Case Presentation: A 16-year-old boy with recurrent pneumonia and elevated IgE levels was diagnosed with CGD through whole exome sequencing (WES). Metagenomic next-generation sequencing (mNGS) identified Burkholderia multivorans in bronchoalveolar lavage fluid, leading to treatment with hematopoietic stem cell transplantation.
Key Findings:
The patient had two point mutations in the CYBA gene, identified through WES.
mNGS facilitated the early identification of Burkholderia multivorans in bronchoalveolar lavage fluid, which was critical for treatment.
The patient was cured following hematopoietic stem cell transplantation.
Interpretation:
The findings demonstrate the importance of mNGS and WES in the diagnosis and treatment of CGD.
Limitations:
The study is based on a single case report, limiting generalizability.
Conclusion:
The case highlights the importance of advanced genetic sequencing techniques in diagnosing and managing rare immunodeficiencies like CGD.
