FTDNA excludes 309 and 315 when evaluating the GD, but they do count 16519 and also insertions/deletions at 522 as steps. FTDNA also counts heteroplasmies as 1 or sometimes 2 steps in the GD, but in most cases I would also ignore the heteroplasmies.

If you ignore the list above and any heteroplasmies, that will give you a better estimate of the number of extra mutations that are significant.
You lost me me at heteroplasmies. Can you explain what that is or how I am to recognize that so as to ignore one? Also, if I am looking at GD=0, would that indicate there are no heteroplasmies to ignore?

I have 8 "extra mutations" of which 5 are the common ones listed above, leaving three not listed above. Would my 5 GD=0 matches also have those 3 "extra mutations" in common and therefore be significant?

The FTDNA mtDNA FAQ has a detailed explanation of heteroplasmies, and there are a few other hot spots that could be ignored. From Phylotree: "The mutations 309.1C(C), 315.1C, AC indels at 515-522, A16182c, A16183c, 16193.1C(C) and C16519T/T16519C were not considered for phylogenetic reconstruction and are therefore excluded from the tree."

Other markers can be extremely volatile in some haplogroups, for example, I would ignore marker 16093 in haplogroup H10.

Which haplogroup are you in, and is there an active volunteer for your haplogroup project?

Thank you for the source suggestion. I will check that out.

I am currently shown as H11a2 by FTDNA, but my project admin for H11 believes I am actually H11a2a.

I appreciate your answering my questions.

Renegade6008, you are a match on my mother's GEDmatch 'X one-to-many' list using the default parameters (500 SNPs,7.0 cM minimum segment). Her kit is T436420. There is also another H11a2a besides you on that list and an H11a2a1, as well as two H11a2's and I believe fifteen H11a's, some of which may not have been tested fully to develop subclades.

You can do the 'X one-to-many' for my mother's kit and click on the downward arrowhead on the mtDNA column if you wish to see the kit numbers.

Hope this is of interest.

Jack, the Gedmatch kit, to which you refer, is that of one of my daughters. Oddly, your mother's kit does not seem to match the kit of anyone else in my daughter's immediate family (parents, twin sister, grandmother) on the 'X' like she does. Not sure what to make of that. Any ideas?

Renegade6008, thanks for the reply. I'll ponder the question with the new info.

It usually means it is a false match.
