New genetic biobank could hold the key to preventing SIDS A state-of-the-art genetic biobank could hold the key to preventing Sudden Infant Death Syndrome (SIDS), potentially saving the lives of hundreds of babies who die from the devastating condition each year. Developed by the University of South Australia, the biobank comprises DNA from 25 babies who have died from SIDS in South Australia. It's the only one of its kind in the Southern hemisphere, and one of only a few that exist in the world. Sudden Infant Death Syndrome (SIDS) is the sudden, unexpected, and unexplained death of an apparently well baby, despite clinical investigations, including autopsy.
