Summary
This study identifies a genetic link between congenital heart defects and bone malformations, suggesting an autosomal dominant inheritance pattern. Familial studies are recommended for early diagnosis and intervention in affected individuals.
Area of Science:
- Medical Genetics
- Pediatrics
- Cardiology
Background:
- Congenital cardiovascular anomalies and osseous system malformations can occur together.
- Understanding the genetic basis of these combined conditions is crucial for diagnosis and prognosis.
Observation:
- Seven patients (six infants, one adult) presented with combined congenital heart defects and skeletal abnormalities.
- Three cases with family pedigrees showed autosomal dominant inheritance, characterized by interauricular septal defects and thumb deformities (polydactyly).
- Four cases without family studies exhibited interauricular septal defects, transposition of great vessels, and osseous malformations like radium agenesis and polydactyly.
Findings:
- Autosomal dominant inheritance was confirmed in cases with family pedigrees.
- Common findings included interauricular septal defects, polydactyly, and thumb agenesis or deformities.
- Two infants with severe congenital heart defects died from heart failure within seven months.
Implications:
- Early familial studies are recommended to identify individuals at risk for these congenital malformations.
- Genetic factors play a significant role in the etiopathogenesis of these combined anomalies.
- Prognosis is closely tied to the type and severity of the congenital cardiac defect.
