Abstract

We present a boy with congenital lymphedema, a congenital heart defect (coarctation of the aorta), and mild dysmorphic features. Clinical impression and targeted investigations ruled out Noonan syndrome and Milroy syndrome, but it was not clear whether or not he had Irons–Bianchi syndrome. We discuss the genomic and lymphoscintigraphy evaluation of this case, and review whether the small number of current case reports represent the original Irons–Bianchi syndrome or variants. We anticipate that ongoing molecular investigations such as Next Generation Sequencing will delineate a currently clinically defined phenotypic spectrum. © 2011 Wiley Periodicals, Inc.
