Abstract
Prenatal sonographic depiction of congenital vertical talus (rocker bottom feet), describing a prominent calcaneus and rounded convex appearance of the ventral aspect of the foot, has been reported with fetal Trisomies 18, 13, 9 HOXD10 mutations and recently 2q13 microdeletion. We present a 24 year old in whom mid-trimester sonographic finding of isolated bilateral rocker bottom feet led to diagnosis of 7q11.23 microdeletion-Williams syndrome. This association has not been reported previously. This case emphasizes the critical assessment of detail microarray upon prenatal sonographic notation of abnormal structural fetal features.
