Summary
This report details a rare case of Weaver syndrome in a young female, highlighting key diagnostic features and potential genetic underpinnings. The study contributes to understanding overgrowth disorders and their genetic basis.
Area of Science:
- Genetics
- Pediatrics
- Medical Case Reports
Background:
- Weaver syndrome is a rare genetic disorder characterized by overgrowth.
- Accurate diagnosis and understanding the genetic basis are crucial for patient management.
Observation:
- A 2-year-9-month-old female presented with persistent pre- and post-natal overgrowth, advanced bone age, and distinctive facial features.
- Key findings included macrocephaly, ocular hypertelorism, micrognathia, large ears, tibial vara, and developmental delay.
- Neurological signs such as cortical atrophy and ventricular dilation were also noted.
Findings:
- The patient's presentation aligns with established criteria for Weaver syndrome.
- Differential diagnosis with other overgrowth syndromes was considered.
- The case suggests potential roles for uniparental disomy and genetic imprinting in Weaver syndrome etiology.
Implications:
- This case expands the clinical description of Weaver syndrome.
- It underscores the importance of considering genetic imprinting and uniparental disomy in diagnosing overgrowth disorders.
- This is the first reported case of Weaver syndrome in the Venezuelan literature, aiding regional medical awareness.
