[Apologies if this eventually turns out to be a double post. About four or
five hours ago I tried to reply through a web-based email service, and the

semi-timely.]

Charles,

May I ask you to look again at your Sorenson value for DYS463? I understand
from Thomas Krahn of biotix that he and Sorenson use the same protocol on
this marker, and the values they provide should thus be identical. I don't
understand how biotix can give you 24 and Sorenson give you 22.

In my own case biotix reports DYS463=24. By trial and error I determined
that Sorenson came up with the same value. You can only get Sorenson's value
by using the "do not adjust" button on their search page and using markers
for which there is no alternative nomenclature.

Only DNAH and RG, to my knowledge, interpret this marker in a way that
produces an allele count that is lower by 2 than what Sorenson and biotix
report. In a sense, FTDNA does not have a dog in this fight because they do
not test DYS463. But they are involved because they allow values for DYS463
to be posted on Ysearch; it is in their interest (everybody's, actually) to
make sure consistent information goes into that field.

One of the reasons I hope FTDNA and DNAH can get over their commercial tiff
and find a way to talk to each other is that issues like this will yield
only to cooperative exchange of relevant information.

But if this issue must be cast in light of competitive business realities,
both firms should know that the satisfaction their customers feel with their
chosen DNA analyst may suffer if obvious questions and inconsistencies are
not addressed by the service providers. Again, I repeat the invitation to
representatives of both firms to comment on the DYS463 issue. I would also
like to hear from the Sorenson representative.

Phil, David, et al:

I have been tested for marker DYS463 by Sorenson Genomics (allele=22)
and Biotix (allele=24). See my labmerge page comment number 13 and
marker number 48 in my data tables for details about the nomenclature
issues for marker DYS463:
