The primary objective of this study is to evaluate the safety and tolerability of the dietary supplement, nicotinamide mononucleotide (NMN), in individuals with dehydrodolichol diphosphate synthase congenital disorder of glycosylation (DHDDS-CDG). This will to contribute to knowledge that will allow healthcare providers to make informed decisions about recommending this dietary supplement in this population.
This is a small cohort, off label treatment study assessing the safety, and tolerability of the over-the-counter supplement, nicotinamide mononucleotide (NMN) in individuals with heterozygous DHDDS-CDG. There is no treatment currently available for this progressive disease and there is evidence that this supplement may be a viable supportive therapy. This study will assess the safety and tolerability of this supplement, as well as examine NMN's effect on clinical manifestations of DHDDS-CDG, including gait abnormalities and hand tremor. This phase 1, open-label study will have a 4 week run-in…
