Microdeletion 4p16.3 in three unrelated patients with Wolf-Hirschhorn syndrome

Wolf-Hirschhorn syndrome (WHS) is a multiple malformation syndrome caused by partial monosomy of 4p16.3. Pitt-Rogers-Danks syndrome, first thought to be a distinct entity, is a similar condition associated with a microdeletion overlapping the WHS critical region. In this paper we evaluate three WHS patients showing a microdeletion of 4p and remarkable development with respect to the clinical spectrum of WHS.
