Hypothesis

The m.14459G > A mitochondrial DNA mutation may lead to Leigh Syndrome or related conditions.

Conclusion

The m.14459G > A mutation is associated with Leigh Syndrome, but its clinical variability remains unexplained.

Supporting Evidence

  • The patient exhibited symptoms like psychomotor delay and seizures.
  • MRI showed bilateral symmetric lesions in the brain.
  • The mutation was confirmed through specific PCR-RFLP assays.

Takeaway

A baby with a rare genetic mutation was studied to understand a serious brain disease called Leigh Syndrome. The mutation can cause different symptoms in different people.

Methodology

Direct sequencing of muscle-derived mtDNA and clinical evaluations were performed.

Limitations

The study is based on a single case, limiting generalizability.

Participant Demographics

15-month-old female patient from nonconsanguineous Italian parents.
