The analysis of correlation showed statistically significant correlations between levels of IgA antibodies to tTG and npG in both DH group (r = 0.4149) and the group of IgA/neutrophil-mediated non-DH dermatoses (r = 0.7890), whereas there was no such correlation in healthy controls (r = 0.2231). Here, CD79A is linked to dermatitis herpetiformis, familial.
