In addition to the fetal complications, they can also cause complications for the mother during pregnancy. [4] Examples include: Mitochondrial trifunctional protein deficiency (MTPD) [3] MCADD, LCHADD, and VLCADD [5] Schematic demonstrating mitochondrial fatty acid beta-oxidation and effects of LCHAD deficiency

SUDC is rare, with a reported incidence in the United States of 1.2 deaths per 100,000 children, compared to 54 deaths per 100,000 live births for SIDs. There are approximately 400 deaths per year of SUDC in the U.S, with over 200 of these cases being the children aged 1–4 years. [3] SUDC deaths have occurred at the following sites: [4]
