Celiac.com 2/13/2003 - According to a recently published large-scale multi-year and multi-center study, 1 in 133, or a total of 2,131,019 Americans have celiac disease. Alessio Fasano, MD, et. al., and colleagues screened 13,145 subjects using serum antigliadin antibodies and anti–endomysial antibodies (EMA). Those who had positive EMA results were screened again for human tissue transglutaminase IgA antibodies and celiac disease-associated human leukocyte antigen DQ2/DQ8 haplotypes, and when possible, intestinal biopsies were also given. Additionally, for those with biopsy-proven celiac disease, 4,508 first-degree relatives and 1,275 second-degree relatives were also screened for the disease. A total of 3,236 symptomatic patients and 4,126 not-at-risk individuals were screened.
The study determined the following:
| Group | Prevalence |
| First degree relatives | 1 in 22 |
| Second-degree relatives | 1 in 39 |
| Symptomatic patients | 1 in 56 |
| Not-at-risk individuals (overall prevalence) | 1 in 133 |

These results are much higher than previous studies have found, and they indicate that celiac disease is perhaps the most common genetic disorder in the United States, as well as one of the most poorly diagnosed diseases.
