Nicotinamide adenine dinucleotide (NAD+) depletion is associated with numerous diseases in humans. Recently it was revealed that genetic blockage of the NAD+ synthesis pathway in humans causes birth defects in multiple organ systems and miscarriage. Additionally, mice with NAD+ deficiency created through dietary restriction of tryptophan and vitamin B3 were shown to have congenital anomalies affecting virtually every organ system along with miscarriage. Perturbations in NAD+/NADH affect mechanisms of teratogenesis presented by Wilson and others, including genetic alterations, altered energy sources, and lack of precursors and substrates needed for biosynthesis.
