Eligibility Criteria

undefined - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Subject is informed and given ample opportunity to consider his/her participation and has given his/her written consent.

5. Study Description

Brief Summary
The current study is a prospective evaluation of the ability of ketosis to shift mitochondrial DNA (mtDNA) heteroplasmy in subjects harboring a known mutation in their mtDNA at position 3243 (A>G). Subjects will be given supplemental medium chain triglycerides (MCTs) for a period of 6 months. mtDNA heteroplasmy will be measured 3 months prior to treatment, at treatment initiation, and 6 months after initiation. The primary objective of the current study is to determine if there is a shift in heteroplasmy in patients harboring the 3243 A>G mtDNA mutation to a more favorable (higher wild-type) profile while in a state of ketosis.
Detailed Description
The current study is a prospective evaluation of the ability of ketosis to shift mitochondrial DNA (mtDNA) heteroplasmy in subjects harboring a known pathogenic mutation in their mtDNA at position 3243 (A>G). Subjects will be induced in to ketosis by administration of supplemental medium chain triglycerides (MCTs) for a period of 6 months. mtDNA heteroplasmy will be assessed 3 months prior to treatment, at treatment initiation, and 6 months after initiation. The primary objective of the current study is to determine if there is a shift in heteroplasmy in patients harboring the 3243 A>G mtDNA mutation to a more favorable (higher wild-type) genotypic profile while in a state of ketosis.
