The sudden death of a child is a tragic occurrence. Of all the child and infant deaths in the United States, more than 10% occur without any apparent cause, compounding the grief of families who have lost their children.[3] These sudden, unexpected deaths typically impact seemingly healthy children and are classified as sudden infant death syndrome (SIDS), sudden unexpected infant death (SUID), or sudden unexplained death in childhood (SUDC). Together, these three entities are thought of as sudden unexpected death in pediatrics (SUDP).[4] Through the generous support of the Isaiah Stone Foundation, CURE Epilepsy funded Dr. Annapurna Poduri and colleagues Rick Goldstein, Hannah Kinney, and Ingrid Holm in Robert’s Program** at Boston Children’s Hospital to explore the genetic basis of SUDP; the hypothesis for this work is that there are common, underlying, genetic mechanisms behind the three entities of sudden childhood death, epilepsy and sudden unexpected death in epilepsy (SUDEP).
Earlier work from these researchers had highlighted a link between SIDS and variants in a gene called SCN1A, which is associated with epilepsy and SUDEP.[1, 5, 6] What was notable is that while this gene is traditionally thought to be related to epilepsy, the children who died suddenly and unexpectedly had no history of seizures or epilepsy. This and other studies have suggested that SUDP is an overarching disorder consisting of rare and yet-undiagnosed diseases with potentially overlapping genetic mechanisms.[1, 7, 8]
