G-L293 microbranch E
G2a1e represents a newly resolved microbranch detected primarily through recent high coverage sequencing efforts in Iran, Armenia and eastern Turkey. Although small, the branch fills an important phylogenetic gap between the better documented G2a1a and the more regionally confined G2a1c and G2a1d lineages. Its structure suggests a founder event during the late Chalcolithic or early Bronze Age among populations on the Armenian–Zagros frontier.
Modern representatives are rare but geographically focused around Armenia, eastern Turkey and northwest Iran. Small clusters exist among Armenian highland communities, Kurdish populations and a few isolated Georgian families. The distribution mirrors zones known for deep G2a1 diversity, reinforcing the idea that the entire L293 radiation was deeply rooted in this highland corridor.
G2a1e forms a microbranch within the L293 clade alongside G2a1c and G2a1d. The branch shows limited downstream structure but enough internal SNP variation to be phylogenetically meaningful. Its upstream position suggests divergence after G2a1c but before some of the most recent L293 derived clusters.
Incorporating G2a1e into the atlas improves the symmetry of the G2a1 section. It acknowledges several newly identified but credible WGS based L293 derivatives that previously lacked representation in broad scale haplogroup references.
