WW domain-containing oxidoreductase-related epileptic encephalopathy in Two Omani Children.

Abstract

Background: Autosomal recessive developmental and epileptic encephalopathy type 28 (DEE28) is a rare genetic disorder that affects children in the early months of life. It is proved to be caused by a pathogenic variance in WW domain-containing oxidoreductase (WWOX) gene. Case presentation: Here, we report a 5-year-old male patient with autosomal recessive DEE28. Whole exome sequencing (WES) test was conducted and resulted in a pathogenic result on WWOX gene pathogenic variant. To our knowledge, these are the first cases reported in Oman. Conclusion: For patients with DEE28, it is essential to take the full family history and genetic workup to assist in the diagnosis. In the future, gene therapy – which is currently being investigated - may help those patients to have a good quality of life and improve the prognosis of the disease.
