8p11 Microduplication Is Associated with Neonatal Stridor

Abstract

We report a term male infant with congenital stridor secondary to tracheomalacia and a mild coarctation of the aorta. Developmental delay was noted upon follow-up. Whole genome SNP microarray analysis showed an ∼846-kb interstitial duplication of the short arm of chromosome 8 (8p11.21p11.1). We report novel clinical findings of this rare genetic condition.
