Caudal regression anomalad (sacral agenesis) in siblings.

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.
