New study in AJG indicates new genetic factors influence CD.
Celiac.com 03/07/2011 - Although the HLA-DQ locus is clearly the strongest genetic factor influencing the development of celiac disease, it is certainly possible that other genes play supporting roles. Identifying these genes could help shed light on why certain genetically susceptible individuals develop celiac while others can happily (and healthily) eat gluten.

NALP1 and NALP3 are genes that encode proteins involved in assembling the inflammasome, which is exactly what it sounds like – a complex of proteins that promotes inflammation. Gain-of function mutations – those that render the protein perpetually active, rather than responsive to activating signals – in NALP3 are known to cause autoinflammatory diseases, and NALP1 polymorphisms have been associated with the autoimmune diseases vitiligo, type I diabetes, and Crohn’s disease. NALP1 is found at high levels in T cells and Langerhans cells, but is also expressed in glandular
