To present a case of a neonate diagnosed with X-linked centronuclear myopathy (XLCNM) and discuss the clinical presentation, management strategies, and the significance of genetic insights.
Approach:
Case Presentation: A male infant born at 36 weeks of gestation with severe asphyxia and low birth weight was admitted shortly after birth. Initial evaluations indicated severe respiratory distress and low muscle tone. Genetic testing via whole exome sequencing confirmed XLCNM due to a rare variant in the MTM1 gene.
Key Findings:
The infant required extensive resuscitation and intensive care but did not stabilize.
Genetic testing identified a rare variant in the MTM1 gene, confirming the diagnosis of XLCNM.
The infant's condition led to the decision to withdraw therapy after extensive treatment efforts.
Interpretation:
This case highlights the need for early recognition of XLCNM and the role of genetic counseling for affected families.
Limitations:
The case report is based on a single patient, limiting generalizability.
The complexities of XLCNM may not be fully captured in this case, which could affect the understanding of its clinical presentation.
Conclusion:
The report emphasizes the role of genetic testing in diagnosing XLCNM in neonates with unexplained symptoms.
