[2] The root level haplogroup JT* has been assigned to an ancient person found at the Colfiorito necropolis in Umbria in central Italy.
[3] The haplogroup has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Taforalt prehistoric site.
[4] One ancient individual carried a haplotype, which correlates with either the JT clade or the haplogroup H subclade H14b1 (1/9; 11%).
[5] This phylogenetic tree of haplogroup JT subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation[1] and subsequent published research.
Maternally inherited ancient mtDNA variants have clear impact on the presentation of disease in a modern society.
