Caudal regression anomalad (sacral agenesis) in siblings
Clinical Genetics
|April 1, 1978
Insights
Two male siblings presented with spinal hypoplasia and congenital heart disease. This rare condition shares features with VATER association and caudal regression, suggesting a potential genetic cause.
Area of Science:
- Genetics
- Developmental Biology
- Pediatric Cardiology
Background:
- Congenital anomalies encompass a range of structural, functional, or metabolic abnormalities present at birth.
- Spinal anomalies, such as hypoplasia of the caudal spine, can occur in isolation or as part of complex syndromes.
- Congenital heart disease (CHD) is a common birth defect, affecting approximately 1% of live births worldwide.
Observation:
- Two male siblings were identified with hypoplasia of the caudal spine.
- Both siblings also exhibited congenital heart disease.
- The observed anomalies suggest a potential overlapping phenotype with known developmental disorders.
Findings:
- The siblings presented with a rare combination of caudal spine hypoplasia and congenital heart disease.
- The clinical presentation showed overlapping features with both VATER association and caudal regression anomalad.
- These findings suggest a possible genetic etiology for the observed disorder.
Implications:
- Further research is warranted to elucidate the specific genetic basis and inheritance pattern of this condition.
- Understanding this disorder can aid in improved diagnosis and genetic counseling for affected families.
- This case highlights the importance of considering syndromic causes when evaluating patients with combined spinal and cardiac anomalies.
Abstract:
Hypoplasia of the caudal end of the spine and associated anomalies were observed in two male siblings who also had congenital heart disease. The disorder has overlapping features with the VATER association and the caudal regression anomalad, and probably has a genetic basis, although the mode of inheritance is not clear.
