Abstract
The Wolf–Hirschhorn syndrome (WHS, OMIM194190) is a contiguous gene deletion syndrome
of the distal part of the short arm of chromosome 4 (4p16 region) characterized by
a distinctive facial appearance, intrauterine and postnatal growth delay, intellectual
disability, and seizures. The WHS clinical spectrum is complex and variable. Typically,
more than 90% of WHS-related patients begin seizures in the first 3 years of life.
In these cases, most of the epilepsy is well controlled, and over half of the patients
stopped having seizures after adolescence. Etiology and/or genetics of their seizures
were unclear. The clinical data on the association between epilepsy and chromosomal
abnormalities is likely to improve our understanding of the functions and mechanisms
of genes related to epilepsy. Future studies would be needed for a deeper understanding
of WHS.
