AMP case report: Celiac genetic health risk screening by NGS in the family of a child with clinical findings of dermatitis herpetiformis and gluten sensitivity
August 2021—Dermatitis herpetiformis (DH) is an autoimmune skin disorder associated with celiac disease and characterized by pruritic, blistering lesions mainly on the elbows, knees, buttocks, lower back, and scalp. Immunopathogenesis is attributed to IgA TG3 antibody immune complexes in the papillary dermis originating from subclinical celiac disease in the gut. Onset occurs at any age, but DH is diagnosed most often in young adults and rarely in children. Individuals of northern European heritage represent the most frequently affected population for DH, with an estimated incidence reported by the National Organization for Rare Disorders of 75.3 per 100,000 people. First-degree family members of patients with DH are at increased risk for both DH and celiac disease.
