}}Plays a major role in ketone body metabolism. Defects cause a 3-ketothiolase deficiency. [[Yasko Methylation|Yasko]] believes it will cause an increase in gut bugs (particularly clostridia) as well as elevated fatty acid metabolites.

This is one of the SNPs reported by [[NutraHacker SNPs|NutraHacker]].
