The microduplication 22q11.2 syndrome has a wide range of clinical manifestations. The phenotype ranges from normal to mental retardation and congenital anomalies. Esophageal atresia/tracheoesophageal fistula (EA/TEF) has recently been linked with the Tbx1 gene mutation located on the long arm of chromosome 22(22q11.21). We report a case with 1.4 Mb 22q11.23 duplication detected by array-CGH. The father of this infant has the same interstitial microduplication but with a normal phenotype. The phenotype seen in our case is type C (3B) esophageal atresia, tracheoesophageal fistula, and ventricular septal defect. Our patient underwent primary repair of OA/TEF malformations, which was later complicated by pneumonia and a recurrent TEF.
