mtDNA is transmitted through the maternal line and its sequence variability, which is
population specific, is assumed to be phenotypically neutral,. However, several
studies have shown associations between the variants defining some genetic
backgrounds and the susceptibility to several pathogenic phenotypes, including
neurodegenerative diseases. Many of these studies have found that some of these
variants impact many of these phenotypes, including the ones defining the Caucasian
haplogroups H, J and Uk, while others, such as the ones defining the T haplogroup,
have phenotype specific associations. In this review, we will focus on those that have
shown a pleiotropic effect in population studies in neurological diseases. We will also
explore their bioenergetic and genomic characteristics in order to provide an insight
into the role of these variants in disease.
