I received several replies and DQ1 seems to be the third gene, and possibly
DQ3 and/or others as a forth one. Not as clear is whether this is a gene
for gluten sensitivity or intolerance only, or can also lead to celiac
disease. It does seem to have GI type symptoms for some and/or neurological
problems as well. For more info on the latter see the Dr. M.
Hadjivassiliou  reference listed below. Some of those who replied feel that
gluten intolerance or sensitivity is a larger group with celiac disease as
a sub group.  Unfortunately many who have symptoms but do not meet the gold
standard for a CD diagnosis may be told that they do not need to follow a
GF diet, to their detriment. E-mail [log in to unmask] if you would like
more info from one layperson on this approach or see references below from
Ma
ry. Another interesting comment was "Blood test results for DQ1 often
vary from the typical Celiac blood test results in that a high Antigliadin
Antibody IgG may be the only blood test/biopsy that comes up positive."
Since I have two copies of DQ1, I had looked into IgG mediated gluten
sensitivity before and my delayed reaction to accidentally ingesting gluten
seems to fit this type of reaction perfectly. I usually don't react until 3
or 4 days later although I may have minor symptoms before then.(I did test
negative for wheat on IgE testing.)

Many thanks for all the responses, they have been very helpful and are most
