Summary
Neonatal progeroid syndrome may present with diverse symptoms, including congenital heart defects and urinary reflux. Autopsy findings suggest this condition might be a heterogeneous phenotype with multiple underlying causes.
Area of Science:
- Pediatrics
- Genetics
- Neonatology
Background:
- Neonatal progeroid syndrome (NPS) is a rare genetic disorder characterized by premature aging features at birth.
- Typical features include intrauterine growth retardation, lipodystrophy, and a wizened facial appearance.
Observation:
- A case of NPS is presented with atypical clinical manifestations.
- The infant exhibited intrauterine growth retardation, absence of subcutaneous fat, and a prematurely aged appearance.
- Additionally, congenital heart defects and urinary reflux were noted, which are not commonly reported in NPS.
Findings:
- Elevated maternal serum alpha-fetoprotein was detected during gestation.
- Late-onset growth retardation was observed after 31 weeks.
- Autopsy revealed normal cerebral myelination, differing from previous reports of sudanophilic leukodystrophy in one NPS patient.
Implications:
- The findings suggest that neonatal progeroid syndrome may represent a heterogeneous phenotype.
- This implies that NPS could arise from multiple distinct causes or genetic mutations.
- Further research is needed to elucidate the diverse etiologies and clinical spectrum of NPS.
