My Family Tree DNA Full Sequence Mitochondrial Analysis Report

Here is the data given me by Family Tree DNA, which I'm currently comparing with that from James Lick. Both sources have categorized my mtDNA as most closely resembling W1-T119C. However, mine has two missing markers and six extras, so I'm not quite sure but I think it means I'm in-between or belong in my own unique group or clade. However, unless the phylotree gets further updating, with my data included, I have to be content with the present conclusion.

"There are numerous other W1 lineages without enough results yet to receive a subgroup designation. As is the case with the non-Finnish, W1a's, W1b's, and W1e's, these all seem to be north European maritime lineages, perhaps descended from a basic W1 lineage in the eastern Baltic Sea around 4,000 years ago.

"One branch sharing the 119 mutation in HVR2 spread to territories on the Baltic and North Atlantic, and Bay of Biscay. Ancient DNA results show W+119 was present in Germany 7300 years ago, in burials of the LBK culture. Finds of the same type continue in the later Schöningen, Salzmünde, and Bernburg cultures through 5000 years ago.

"One sharing the 16295 mutation arose around 3,000 years ago and is found today in the Netherlands and the British Isles."
This is the link directly tied to the T119C mutation.

This explains my unusual mutations:
"MTDNA Mutations

"The most common mutations are a change in a letter at a location to its complementary letter - A to G, G to A, C to T, or T to C.

"Next most common are insertion of an extra letter. These are represented in your results by a dot, followed by the number of insertions. For example, 315.1C - meaning an extra C was inserted after 315C; or 315.2C - meaning two extra C's were inserted after 315C.

"Deletions can also occur, where a letter in the sequence is missing. These are indicated by a dash, for example 16183-.

"Occasionally the test results show 'heteroplasmy' - meaning the mtdna in your cells shows multiple results for the same position. This can happen because a single cell contains hundreds of thousands of mtdna copies, groups of which may have mutated and have different letters at the same location; and your results are based on the average for many millions of cells, some of which may all contain a certain mutation, while others are unchanged. These ambiguous results are indicated by the letters Y (C or T - example 16093Y); R (A or G - example 16034R); M (A or C - example 16183M); W (A or T - example 16189W); N (G or A or T or C - example 16192N). U, S, M, K, V, H, B, D, and X are also used to indicate other combinations of results for the same location."
