Moebius syndrome with total anomalous pulmonary venous connection

Area of Science:

• Genetics and Developmental Biology
• Pediatric Cardiology
• Neurology

Background:

• Moebius syndrome is a rare congenital neurological disorder characterized by facial nerve palsy and potential cranial nerve deficits.
• Cardiac anomalies are infrequently associated with Moebius syndrome, with only four prior cases documented in medical literature.
• Total anomalous pulmonary venous connection (TAPVC) is a severe congenital heart defect where pulmonary veins do not connect normally to the left atrium.

Observation:

• This report presents a novel case of Moebius syndrome.
• The patient exhibited supracardiac total anomalous pulmonary venous connection (TAPVC), a rare cardiac anomaly.
• This specific combination of Moebius syndrome and supracardiac TAPVC has not been previously described.

Findings:

• The case highlights an extremely rare co-occurrence of Moebius syndrome and supracardiac TAPVC.
• This finding expands the known spectrum of malformations associated with Moebius syndrome.
• The successful identification and characterization of this rare combination are crucial for understanding the syndrome's variability.

Implications:

• This case underscores the importance of comprehensive screening for cardiac anomalies in patients diagnosed with Moebius syndrome.
• Further research into the genetic and developmental pathways may elucidate the link between Moebius syndrome and complex cardiac defects like TAPVC.
• Understanding these rare associations can improve diagnostic approaches and patient management for congenital malformation syndromes.
