Summary
Oculodentodigital dysplasia, a rare genetic disorder, was diagnosed in a 35-year-old man based on distinctive facial features, small corneas, and dental abnormalities. Atypical digital findings, including near-complete absence of the right foot, were noted.
Area of Science:
- Medical Genetics
- Clinical Dysmorphology
Background:
- Oculodentodigital dysplasia (ODD) is a rare autosomal dominant disorder characterized by craniofacial, dental, and limb anomalies.
- Previous literature describes typical features including a prominent forehead, midface hypoplasia, enamel hypoplasia, and digital abnormalities.
Observation:
- This report details a case of ODD in a 35-year-old male presenting with characteristic facies, microcornea, and dental dysplasia.
- The patient exhibited digital findings that were largely consistent with ODD, but included an atypical presentation of almost complete aplasia of the right foot.
Findings:
- The diagnosis of ODD was confirmed through clinical examination, highlighting the constellation of ocular, dental, and digital manifestations.
- The presence of near-complete aplasia of the right foot represents a significant, albeit consistent, variation in the digital phenotype of ODD.
- Mental retardation was observed, but its direct association with ODD remains unclear, suggesting potential for coincidental occurrence.
Implications:
- This case expands the known phenotypic spectrum of oculodentodigital dysplasia, particularly regarding digital anomalies.
- Further research is warranted to elucidate the genetic underpinnings and variability of ODD, and to clarify the potential link between ODD and cognitive impairment.
- Accurate diagnosis and understanding of ODD's phenotypic variability are crucial for genetic counseling and patient management.
