HLBA27 genetic marker, more info?

[Todd Andrews]

I have been told that I have the genetic marker HLBA27, which is
supposed to mark me as susceptable to ryghters(sp?) syndrome.
I will assume that this marker/syndrome combination is truthful, but I
will also question the diagnosis.
I am curious about further susceptabilities to other
syndromes/problems. For anyone familiar with said marker, thanks for
any information.

Thank you,
                             -T
