Results suggest that the less-frequent E69 variants (non-*0201\/*0202 alleles) might be associated with greater risk of CBD. In this study, we sought to define specific E69-carrying alleles and their amino acid sequences in the DP peptide binding groove, as well as their relationship to CBD and BeS risk, using the largest case control study to date. We enrolled 502 BeS\/CBD subjects and 653 beryllium-exposed controls from three beryllium industries who gave informed consent for participation. Non-Hispanic white cases and controls were frequency-matched by industry. HLA-DPB1 genotypes were determined using sequence-specific primer PCR. The E69 alleles were tested for association with disease individually and grouped by amino acid structure using logistic regression. The results show that CBD cases were more likely than controls to carry a non-*02 E69 allele than an *02 E69, with odds ratios (95% confidence interval) ranging from 3.1 (2.1\u20134.5) to 3.9 (2.6\u20135.9) (p &amp;lt; 0.0001). Polymorphic amino acids at positions 84 and 11 were associated with CBD: DD versus GG, 2.8 (1.8\u20134.6), p &amp;lt; 0.0001; GD versus GG, 2.1 (1.5\u20132.8), p &amp;lt; 0.0001; LL versus GG, 3.2 (1.8\u20135.6), p &amp;lt; 0.0001; GL versus GG, 2.8 (2.1\u20133.8), p &amp;lt; 0.0001. Similar results were found within the BeS group and CBD\/BeS combined group. We conclude that the less frequent E69 alleles confer more risk for CBD than does *0201. Recent studies examining how the composition and structure of the binding pockets influence peptide binding in MHC genes, as well of studies showing the topology of the TCR to likely bind DPB1 preferentially, give plausible biological rationale for these findings.<\/jats:p>","DOI":"10.4049\/jimmunol.1200798","type":"journal-article","created":{"date-parts":[[2012,9,13]],"date-time":"2012-09-13T02:37:51Z","timestamp":1347503871000},"page":"4014-4023","source":"Crossref","is-referenced-by-count":31,"title":["Chronic Beryllium Disease, HLA-DPB1, and the DP Peptide Binding Groove"],"prefix":"10.1093","volume":"189","author":[{"given":"Lori J","family":"Silveira","sequence":"first","affiliation":[{"name":"National Jewish Health , Denver, CO 80206"},{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erin C","family":"McCanlies","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health , Morgantown, WV 26505"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tasha E","family":"Fingerlin","sequence":"additional","affiliation":[{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael V","family":"Van Dyke","sequence":"additional","affiliation":[{"name":"National Jewish Health , Denver, CO 80206"},{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margaret M","family":"Mroz","sequence":"additional","affiliation":[{"name":"National Jewish Health , Denver, CO 80206"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Strand","sequence":"additional","affiliation":[{"name":"National Jewish Health , Denver, CO 80206"},{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew P","family":"Fontenot","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Colorado Denver , Denver, CO 80045"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalie","family":"Bowerman","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Colorado Denver , Denver, CO 80045"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana M","family":"Dabelea","sequence":"additional","affiliation":[{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine R","family":"Schuler","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health , Morgantown, WV 26505"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ainsley","family":"Weston","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health , Morgantown, WV 26505"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa A","family":"Maier","sequence":"additional","affiliation":[{"name":"National Jewish Health , Denver, CO 80206"},{"name":"Colorado School of Public Health, University of Colorado Denver , Denver, CO 80002"},{"name":"Department of Medicine, University of Colorado Denver , Denver, CO 80045"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2012,10,15]]},"reference":[{"key":"2025032409295575000_r1","first-page":"937","article-title":"The natural history of beryllium sensitization and chronic beryllium disease","volume":"104","author":"Newman","year":"1996","journal-title":"Environ.
