HLA-ABC and DR Antigens in Celiac Disease
A Study in a Pediatric Italian Population1
This work was supported by the Italian CNR ‘Progetto Finalizzato di Medicina Preventiva Sottoprogetto MPP4’.
Abstract
HLA phenotypes of 64 Italian pediatric patients with celiac disease (CD) were compared with those of a group of healthy controls. DR3 and DR7 are significantly increased as reported in other populations. In addition an increase of heterozygotes DR5/DR7 was observed in our patients. The Hardy-Weinberg distribution in the patients group shows a disequilibrium due to the genotype DR5/DR7. Our data confirm that more than one HLA gene product is associated with CD: one with DR3 and the other with DR7.
