Haplogroup Q-M346 is a subclade of Y-DNA Haplogroup Q. Haplogroup Q-M346 is defined by the presence of the M346 Single Nucleotide Polymorphism (SNP).
Q-M346 was discovered in Central Asia and announced in Sengupta 2006. A latter paper suggested that its ancestral state was isolated to India, but this has since been refuted by its presence in West Asia, Europe and the Americas.
Q-M346 has a wide distribution across much of Asia.
In the Americas, the founding paternal lineages include those who are Q-M346 but do not belong to the Q-M3 lineage.
Q-M346 is marked by the presence of the M346 SNP. Since the discovery of M346 several additional SNPs have been found to also be associated with Q-M346. These SNP's include: L56 and L57. These SNPs appear to be "parallel" to M346.
This is Thomas Krahn'sâÂÂof the Genomic Research CenterâÂÂdraft tree, Proposed Tree, for haplogroup Q-M346. The first three levels of subclades are shown. Additional detail is provided on the linked branch article pages.
