Genetic Heart Defects Rarely the Cause of SIDS, Research Shows

MONDAY, March 12, 2018 (HealthDay News) — Heart diseases linked to genetic flaws cause far fewer sudden infant death syndrome (SIDS) cases than once thought, a new study finds.

In a genetic investigation of 419 SIDS cases, Mayo Clinic researchers found that genetic mutations associated with heart disease accounted for about 5 percent.

Previous studies have suggested that such mutations could cause up to 20 percent of SIDS deaths.
