Mitochondrial haplogroups

Polymorphism: Mitochondrial haplogroups

Variant Type: Locus
Location: MT

- Symbol: mtDNA


Differences between mtDNA haplogroup frequencies were significantly different between groups of ages (p=0.01). Compared to the old, haplogroup H was less frequent than among the middle-aged subjects and infants (p=0.001 and p=0.00001), whereas haplogroups U and J were more common.
