Summary
Infants with Down syndrome (DS) have a significantly higher incidence of oesophageal atresia (OA). This study confirms a non-random, potentially causal link between DS and OA, highlighting the need for further investigation.
Area of Science:
- Medical Genetics
- Pediatric Surgery
- Developmental Biology
Background:
- Down syndrome (DS) is associated with congenital anomalies.
- Previous studies suggested a possible link between DS and oesophageal atresia (OA).
Purpose of the Study:
- To investigate the association between Down syndrome and oesophageal atresia using data from the Sicilian Registry of Congenital Malformations.
- To determine if the observed association is statistically significant and potentially causal.
Main Methods:
- Retrospective analysis of data from the Sicilian Registry of Congenital Malformations.
- Calculation of incidence rates of oesophageal atresia in infants with and without Down syndrome.
Main Results:
- The incidence of oesophageal atresia in infants with Down syndrome was found to be 0.9%.
- This incidence is over 30 times higher than expected and higher than previously reported (0.5%).
Conclusions:
- The association between Down syndrome and oesophageal atresia is non-random.
- The consistent observation across populations suggests a potential causal relationship between Down syndrome and oesophageal atresia.
