A metabolomic analysis of sudden infant death syndrome (SIDS) cases revealed 35 significant potential metabolite predictors, including ornithine and 5-hydroxylysine. The study, published in eBioMedicine, involved 300 infants, with results shedding light on potential diagnostic biomarkers associated with the disease. The findings contribute to the understanding of SIDS, emphasizing the need for validation in independent cohorts to refine their clinical relevance.
