Haplogroup R and Subclades

DNA Helix

Haplogroup R is defined by rs2032658 also known as M207. The group is believed to have developed about 19,000 to 34,000 years ago in Central Asia. In modern times descendants are common in Europe, South Asia, and Central Asia.

This site's emphasis is on collecting the original BAM raw data when possible to construct a phylogentic tree using the GRCh38 human genome reference. To contribute please use the Submission Tool.

Supporting data from publicly available Haplogroup R related repositories is integrated as a service to the community. The Kits page contains a cross-reference list to track sample donors between labs. This allows testers to be placed to their closest branch in the Experimental Tree. To aid converting coordinates of variants placed in the tree, consult the Variant Index.

YSEQ customers are encouraged to join Group 223: haplogroup-r.org Public Results. This group is the primary location monitored to collect new sequencing results.


2017-07-04: The original haplogroup classifier written in 2015 has been replaced with a new algorithm. The new approach fixes all known edge-case problems with recurrent mutations as long as sufficient SNPs are tested. This will enable phase 1 of a new automated tree builder for NGS testers. The current tree will be archived and a fresh version developed from the 2017 Y Tree skeleton is coming using only BAM submissions to establish branching. This reset will shed branches not supported the Call Matrix.
