Two Cases of Scimitar Syndrome Associated with Multiple Congenital Skeletal Anomalies and Lacking Abnormalities by Genomic Microarray Analysis

Abstract

Scimitar syndrome is a congenital anomaly occurring in approximately 1/50 000 births, consisting of partial anomalous pulmonary venous return, right lung hypoplasia, and several associated defects. The condition generally has significant morbidity and mortality, but the underlying cause is poorly understood. In this report, we describe 2 autopsy cases of Scimitar syndrome associated with multiple skeletal anomalies and attempt to characterize possible genetic abnormalities in this condition. In light of these findings, we discuss the embryology and direct timing during development of the anomalies associated with this syndrome.
