Since the enzyme encoded by the HMGCL gene is also involved in leucine catabolism, mutations in HMGCL also result in defects in metabolism of this amino acid and consequently leads to accumulation of leucine metabolites, 3-hydroxy-3-methylglutaric acid, 3-methylglutaconic acid, 3-methylglutaric acid, and 3-hydroxyisovaleric acid
Several studies have found that how long B12 remains in the system can depend on underlying factors such as tendencies towards developing certain diseases and lifestyle choices

Because nicotinamide would otherwise re-enter the NAD+ salvage pathway through NAMPT and NMN, NNMT activity sits at a junction between cellular methylation capacity and NAD+ regeneration, which is why the enzyme became a target after Kraus and colleagues (Nature, 2014) reported the consequences of antisense Nnmt knockdown in white adipose tissue and liver
It improves insulin sensitivity. Glucose and insulin measurements changed in diet-induced obese mice
