Anti-TRPV2 Autoantibody Linked to Sudden Infant Death Syndrome | Circulation
As a leading cause of infant death, sudden infant death syndrome (SIDS) remains a perplexing diagnosis with no clear underlying biological substrate. 1 In the past decade, studies have emerged demonstrating that circulating autoantibodies targeting cardiac antigens can underlie life-threatening arrhythmias. 2 Because autoimmunity as a cause of SIDS has not yet been explored, we screened infant serum samples for the presence of autoantibodies targeting cardiac ion channels and examined how immunoglobulins
