DQB1*x?

[Guest guest]

I was reviewing the results of my gene test for Celiac today to compare it to my

son's results, which I just received. Anyway, I called my doctor and his patient

representative called me back. I asked her which HLA alleles I tested positive

for. She said I tested postive for the DQ2 alleles DQB1*02 and DQB1*x. When I

asked her what the x was she said she didn't know, she was just reading the

report verbatim. (She wasn't very helpful).

Does anyone know what DQB1*x means? I have never heard of that and couldn't find

the info online. Does it maybe represent how many copies were detected of the

DQB1?

I'm confused!

I've seen "x" as indicating no protective alleles in diabetic and other testing , as in the following Eur J Clin Invest. 1995 Feb;25(2):106-12 paper, Effect of genetic risk load defined by HLA-DQB1 polymorphism on clinical characteristics of IDDM in children: "When comparing subjects with the DQB1*0302/0201, DQB1*0302/x, DQB1*0201/x, or other DQB1 genotypes (x = no protective allele)...." But this is just an example of one online source. You should ask to talk to another doctor, particularly a gastroenterologist with DNA testing knowledge, to get the real answer in relation to your tests.
