When compared in this way, tTG IgA, GAF-3x IgA and IgG, DGP IgA and DGP Screen had significantly higher titers in severe (Marsh IIIb-c) versus partial atrophy (Marsh IIIa) (tTG IgA EL: 48±21 vs 257±143, p = 0.04; tTG IgA BF: 251±137 vs 484±189, p = 0.02; GAF-3X IgA: 78±24 vs 170±43, p = 0.005; GAF-3x IgG: 55±21 vs 148±46, p = 0.005; DGP Screen: 41±17 vs 84±33, p = 0.03; DGP IgA: 21±5 vs 39±8, p = 0.009). Here, CD79A is linked to Atrophy.
