Moebius syndrome with Taussig-Bing anomaly

Area of Science:

• Pediatrics
• Genetics
• Cardiology

Background:

• Moebius syndrome is a rare neurological disorder characterized by congenital facial nerve palsy.
• Taussig-Bing anomaly is a complex congenital heart malformation involving aortic transposition, pulmonary artery abnormalities, and ventricular septal defect.

Observation:

• A 6-year-old male presented with dysphagia, crying/smiling difficulties, exertional cyanosis, facial dysmorphism, clubbing, polydactyly, and right-sided facial nerve palsy.
• Clinical examination and investigations confirmed findings consistent with both Moebius syndrome and Taussig-Bing anomaly.

Findings:

• The patient exhibited a combination of neurological and cardiac malformations.
• This case represents the first reported instance of the simultaneous occurrence of Moebius syndrome and Taussig-Bing anomaly.

Implications:

• This case highlights the importance of comprehensive evaluation in children with complex congenital anomalies.
• Further research may elucidate potential shared genetic or developmental pathways underlying these co-occurring conditions.
• Understanding this rare association can improve diagnostic approaches and patient management strategies.
