Science solves genetic mystery behind fatal brain disorder in babies and children
Researchers at King Abdullah University of Science and Technology (KAUST) and King Faisal Specialist Hospital and Research Center (KFSHRC) identify a previously unknown cause of a fatal newborn brain disorder, giving long-awaited answers to families whose children were affected by the disease.
Scientists have uncovered the genetic cause of a rare, fatal brain disorder that strikes babies and young children, providing much-needed answers for families who have struggled with uncertainty. The discovery, led by researchers at King Abdullah University of Science and Technology (KAUST) and King Faisal Specialist Hospital and Research Center (KFSHRC), links the condition to changes in a gene called VPS25.
This gene is crucial for maintaining nerve cells in the brain, and its mutations disrupt critical biological processes that affect the development and structure of the brain. The research, published in Genome Medicine, involved studying five unrelated families from Saudi Arabia, Europe, and North America. By comparing these cases, the scientists discovered that the same genetic mutation appeared in all five families, identifying the previously unknown disorder.
This breakthrough allows clinicians to recognize the condition through genetic testing during pregnancy, offering hope and clarity to affected families. Knowing the genetic cause can provide comfort and enable informed decisions about future pregnancies. The study highlights the importance of collaborative efforts between clinicians and researchers in unraveling complex genetic mysteries.
