U8a1 (mtDNA)

For people who have tested and are assigned the maternal haplogroup U8a1 or who are believed to have had that maternal haplogroup based on descendants tested.

Defining Mutations

• (to be added)

Haplogroup K (named Katrine by Bryan Sykes) makes up a sizeable fraction of European and West Asian mtDNA lineages. It is now known it is actually a subclade of haplogroup U8b'K, and is believed to have first arisen in northeastern Italy. Haplogroup UK shows some evidence of being highly protective against AIDS progression.

Distribution

• U8a: The Basques have the most ancestral phylogeny in Europe for the mitochondrial haplogroup U8a, a rare subgroup of U8, placing the Basque origin of this lineage in the Upper Palaeolithic. The lack of U8a lineages in Africa suggests that their ancestors may have originated from West Asia.
• U8b: This clade has been found in Italy and Jordan.
