o yeah u r right kmp.
i read BRS immuno in which it's written that dermatitis herpatiformis which is actually not caused by herpes but it is an allergy to gluten, a protein found in wheat and some other grains, so i thought this DR3.

i also read the FA but i forgot this thing that it's written in FA.

so now which one right.
DR2 OR DR3?

PLS clear this points, these r very minor things but some times we r doing mistakes.

Celiac disease is associated with dermatitis herpitiformis.

HLA B8 Dr3 and DQ2 are associated with it.

For hay fever it is HLA DR2.
