Summary
A stillborn male infant presented with agnathia, a rare congenital condition. The case highlights associated malformations and normal chromosomal analysis in the parents, suggesting a sporadic occurrence.
Area of Science:
- Medical Genetics
- Developmental Biology
- Teratology
Background:
- Agnathia, a severe congenital anomaly, is characterized by the absence of the jaw.
- This condition is exceedingly rare, with limited documented cases.
- Understanding the etiology and associated anomalies is crucial for genetic counseling and research.
Observation:
- A 32-week male stillborn presented with agnathia.
- Associated anomalies included microstomia, microglossia, type III microtia, meatal atresia, and vertebral clefts (D7, D10).
- The infant was part of a healthy, non-related Algerian couple with normal chromosomal analyses.
Findings:
- The stillborn male exhibited a complex pattern of craniofacial and vertebral malformations.
- Normal chromosomal analysis in both parents and proband suggests a non-syndromic, likely sporadic, etiology.
- The presence of multiple congenital anomalies points to a disruption in early embryonic development.
Implications:
- This case contributes to the limited literature on agnathia and its associated anomalies.
- Further research into the genetic and environmental factors influencing jaw development is warranted.
- Accurate diagnosis and genetic counseling are vital for families experiencing such rare congenital conditions.
