What causes SIDS? Genetics study suggests it’s more than unsafe sleep

USA News

The cause of sudden infant death syndrome, or SIDS, continues to be a medical mystery but a new study suggests genetics may play a role.

Over the course of 39 years, researchers found siblings of infants who died of SIDS had a four-fold higher risk of dying suddenly compared to the general population, according to the report published in JAMA Network Open. 

The large study reinforces previous research that shows SIDS may be more of a medical problem than previously thought, said Dr. Richard Goldstein, director of the Robert’s Program on Sudden Unexpected Death in Pediatrics at Boston Children’s Hospital.

“The general bias is that this is a sleep accident and the challenge for people looking at the science here is to advocate on behalf of the families and look harder,” he said.
