Correction: no evidence of an association between the T16189C mtDNA variant and late onset dementia (Gibson et al)

We believe that the title of Chinnery et al’s paper should be corrected because the data the authors present do not include an analysis of the 16189 variant of mtDNA (Table 1). View this table: Table 1 Sequences of identified variants We defined the 16189 variant as the DNA sequence associated with a polydC tract,2 resulting from a T16189C transition that may generate heteroplasmic length variation, table 1. Heteroplasmic length variation does not occur when the polymeric tract is interrupted by a c→t transition, which occurs at several different sites but commonly at nucleotice 16186 or …
