Abstract
Wolf-Hirschhorn syndrome (WHS, OMIM 194190) is one of the most common microdeletion syndromes, represented by a heterozygous deletion of the short arm of chromosome 4 (4p16.3). The main clinical features of patients with WHS include: craniofacial features - “Greek warrior helmet”, prenatal and postnatal growth deficiency, developmental disability of variable degree, and seizures. To date, several mechanisms for the formation of 4p16.3 deletions and several critical regions responsible for phenotypic manifestations in patients have been described. In our study, we present five cases of 4p16.3 deletion with different origins and mechanisms of formation.
