Objective:

To report a novel clinical case of a patient with DOHH-related syndrome and expand the phenotypic spectrum associated with this condition, as observed in the clinical presentation.

Key Findings:
  • Increased nuchal translucency was observed prenatally.
  • Postnatal findings included dilated cardiomyopathy and hypoparathyroidism.
  • The patient exhibited milder neurodevelopmental impairment compared to previously reported cases, with no growth restriction.
Interpretation:

This case expands the phenotypic spectrum of DOHH-related disorders, including cardiomyopathy and hypoparathyroidism.

Limitations:
  • Only one case is reported, necessitating further cases to confirm associations.
  • The study relies on genetic testing and clinical observations without extensive longitudinal data.
Conclusion:

The findings highlight the importance of long-term follow-up for accurate phenotypic characterization.
