Summary
This study describes a Japanese infant diagnosed with megalocornea-mental retardation (MMR) syndrome. The infant presented with megalocornea and developmental delays, aligning with Verloes type MMR syndrome.
Area of Science:
- Genetics
- Pediatrics
- Ophthalmology
Background:
- Megalocornea-mental retardation (MMR) syndrome is a rare genetic disorder.
- Understanding the phenotypic spectrum of MMR syndrome is crucial for diagnosis and management.
Observation:
- A Japanese male infant presented with key features of MMR syndrome.
- Clinical observations included megalocornea (13 mm corneal diameter) without glaucoma.
- Additional findings were developmental retardation, hypotonia, frontal bossing, high-arched palate, carp-like mouth, micrognathia, and delayed myelination.
Findings:
- The infant's presentation strongly suggests a diagnosis of megalocornea-mental retardation syndrome.
- The specific constellation of features aligns with the Verloes classification of MMR syndrome.
Implications:
- This case contributes to the understanding of MMR syndrome's clinical variability.
- Early identification and classification of MMR syndrome are vital for appropriate pediatric care and genetic counseling.
