ISOGG Group Gears Up For SNP Tsunami

The International Society of Genetic Genealogists (ISOOG) is a totally voluntary organization that does not charge dues. However, since 2006 it has been responsible for maintaining the Y-DNA Haplogroup Tree 2013 for researchers and testing labs around the world. The number of SNPs being discovered has been exploding since the end of 2010 and this is just the beginning. The recent wave of newly discovered SNPs have resulted from the Walk the Y, GENO 2.0 and 1,000 Genomes projects as well as the normal discovery processes of investigation by academics and citizen scientists.

The tsunami has yet to come. Geno 2.0 has not yet published all its SNPs. Treasure troves of additional SNPs from FullGenomes and FTDNA’s Big Y tests loom just over the horizon. These have the potential to identify and place thousands of here-to-fore unknown SNPs. Many of these will be leaves toward the ends of branches on the Y-DNA Haplogroup Tree. They will be recent enough to connect with the documented trees by genealogists. 

In anticipation of this bounty and the chaos that may accompany it, those members of the ISOOG group who maintain this tree who were able to gather in Houston on Saturday planned for this event.

It is clear that our processes need to be reorganized and streamlined if we are going to be able to continue to serve the genetic genealogy community and researchers in related disciplines in a timely basis.
