Novel Homozygous Mutation in the WWOX Gene Causes Seizures and Global Developmental Delay: Report and Review.

ABSTRACT: The WWOX gene has a WW domain containing oxidoreductase, which is located at the common fragile site FRA16D at chromosome 16q23. WWOX is a tumor suppressor gene that has been associated with several types of cancer such as hepatic, breast, lung, prostate, gastric, and ovarian. Recently WWOX has been implicated in epilepsy, where studies show homozygous loss-of-function mutation lead to early-infantile epileptic encephalopathy, spinocerebellar ataxia, intractable seizures and developmental delay, and early lethal microcephaly syndrome with epilepsy. Here we investigate two consanguineous Saudi families and we identified three probands with epileptic encephalopathy. Whole exome sequencing revealed a novel homozygous mutation in the WWOX gene in one proband. In addition,
