Lammi et al. (13) analyzed the performance of the anti-DGP assay as compared to TTG-IgA in the diagnosis of 92 children with biopsy-confirmed CeD and found that the anti-DGP assay (IgG and IgA) is as useful as the TTG-IgA assay for detecting CeD in children with sensitivity and specificity > 90% with the area under the ROC curve of 0.99 for both classes of antibodies. This evidence concerns the gene CD79A and cranioectodermal dysplasia.
