For those of us who have had the genetic testing done, it is interesting to share and compare
.
95% of all those with celiac disease will show one of two genetic markers,
HLA DQ2 (90%) or
HLA DQ8 (5%). As many as thirty percent of the population carry this genetic makeup but only one percent develop Celiac Disease.
Another marker, HLA DQ1, has been identified by both Dr. Kenneth Fine and Dr. Marios Hadjivassilou as being associated with a Non-Celiac Gluten Sensitivity. While those who carry HLA DQ1 rarely show villous atrophy, it does happen on occasion. About 1-2% of biopsy proven celiacs carry the HLA DQ1 gene, so it may be questionable practice to rule out Celiac Disease soley by the absence of the main genes (HLA DQ2 or HLA DQ8).
While HLA DQ1 is not recognized by most celiac experts as being associated with celiac disease, Dr. Hadjivassilou has found it in 20% of his gluten sensitive (antigliadin positive) neurological patients. The remaining 80% have either HLA DQ2 or HLA DQ8 consistent with the celiac population.
