R1b SNP update July 30, 2006

The R1b SNP file is updated

www.geocities.com/mcewanjc

We have had 13 new or revised entries in the past week and now stand at 245 entries

Salient issues

* We have a new S28+ entry that was classified as R1bSTR43. This group makes up 8% of Western European R1b and although at least one individual has tested S28- I feel based on this test result and geographical concentration that many in this group may be S28+.

* Although tests between two labs are still being reconciled we

appear to have another P25- M269+ and this one appears to be associated with strange RecLOH revent that has left a gggg profile at DYS464x.

As usual if you have any new data or entries or notice any errors please contact
