In human genetics, Haplogroup L4a is a human mitochondrial DNA (mtDNA) haplogroup. It is a small African haplogroup.[1] It was once called L7 and considered its own branch of L. It was determined to be a subclade of L4 and renamed L4a by Behar et al. in The dawn of human matrilineal diversity.[2]




This phylogenetic tree of haplogroup L4a 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.
