This is the home page for men proven or predicted to have the L1263 mutation. Also listed
here is the subgroup of L1263, consisting of men who have the marker value oddity of
DYS392=10. Markers are not ideal for defining a subgroup because they are subject to
additional mutations, unlike the L1263 SNP mutation. When whole Y-DNA sequencing
identifies a defining SNP mutation for the DYS392=10 subgroup, they will be moved to
their own page.
The above diagram shows Z1263's position in the G tree. It is the youngest of a
series of mutations, each one covering fewer persons as the tree branched.
All Z1263 men have all the mutations shown above it in the tree.
A separate page exists for each of these mutations and the persons covered by them.
See tabs on left. The G-Z2003, G-L140, G-P287 and G-M201 pages have significant
L1263 has one sister subgroup defined by SNP mutation Z2017.
Age of L1263
The overall age of the L1263 group with its subgroups is probably 2500 to 3500 yrs
old. Whole sequencing of Y-DNA would likely provide a more accurate time estimate.
The DYS392=10 subgroup likely shares a common male ancestor within the last 500
to 600 yrs. But the mutation may have existed in earlier generation than that of
the most recent common ancestor.
Geographical Distribution of L1263
Whether in the overall L1263 group or its subgroup, members seem a mix of men
reporting ancestry in a geographical belt extending from England to Germany.
Origins of L1263
As membership in the L1263 group fills in, the origins may come into better
focus, but the origin in perhaps the 2500-3500 year ago period makes
sorting out possibilities a bit complex. Whole sequencing of Y-DNA will
improve what we know about the group and its nearest marker matches.
This subgroup is too new for maps to have appeared in research studies. The G
subgroups in the G project have their own maps.
Look at top left of map and choose the L1263 subgroup and its DYS392=10 subgroup.
Because it is so new, researchers have not mentioned L1263 in their studies.
