Key Clinical Message Studies have shown that difference in mt DNA mutation load among tissues is a result of postnatal modification. We present five family members with the m.8344A>G with variable phenotypes but uniform intrapersonal distribution of mutation load, indicating that there is no postnatal modification of mt DNA mutation load in this genotype.
