For people who have tested and are assigned the maternal haplogroup K2a or who are believed to have had that maternal haplogroup based on descendants tested.

Defining Mutations

• Coding mutations 709, 4561
• HVR mutation 152

Origin

Haplogroup K has an estimated age of about 12,000 years. In his popular book The Seven Daughters of Eve, Bryan Sykes named the originator of the K haplogroup Katrine. (Source: Wikipedia, Haplogroup U (mtDNA))

Distribution

Haplogroup K 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.
