Lineages belonging to haplogroup A2 also comprise the majority of the mtDNA pool of the Inuit and their neighbors, the Chukchis, in northeasternmost Siberia.

[19] Newly defined clade A27 only discerned so far in Newar and Nepali-mix coalesce at ~ 8.4 Kya suggesting their ancient origin and potentially insitu differentiation in Nepal.

[19] This phylogenetic tree of haplogroup A subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[3] and subsequent published research.

The mummy "Juanita" of Peru, also called the "Ice Maiden", has been shown to belong to mitochondrial haplogroup A.

[43][44] In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of this mtDNA haplogroup Aiyana.
