The diagnosis of celiac disease is typically made with a combination of serological testing, including tissue transglutaminase (TTG IgA), anti-endomysial (EMA IgA), and deamidated gliadin (DGP) antibodies, as well as upper endoscopy with biopsy findings of villous blunting, villous atrophy, or crypt hyperplasia [1, 2]. Here, CD79A is linked to celiac disease.
