Wolf-Hirschhorn syndrome (WHS) is a multiple malformation syndrome caused b
y partial monosomy of 4p16.3. Pitt-Rogers-Danks syndrome, first thought to
be a distinct entity, is a similar condition associated with a microdeletio
n overlapping the WHS critical region. In this paper we evaluate three WHS
patients showing a microdeletion of 4p and remarkable development with resp
ect to the clinical spectrum of WHS. Copyright (C) 2001 S. Karger AG, Basel
