Insights
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.
Abstract:
The study included six infants and one adult of congenital cardiovascular anomalies and malformations of the osseum system. In three cases with family pedigree studied, an autosomal dominant character was found; all of them had interauricular defect septum and characteristic congenital deformities of the thumb with polydactyly and one with affection in upper and lower extremities. In the other four patients without family study, interauricular septal defect and transposition of vessels was proved; the osseum malformations were radium agenesia, polydactyly and thumb agenesia. The importance of the genes and the environmental participation and etiopathogenic mechanism are discussed. The prognostic is focussed within type and severity of the congenital cardiac defect; in this study, two infants died within 3 and 7 months of heart failure. These congenital malformations were proved to have autosomal dominant inheritance; we recommend the familial study in all these cases.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
