Loss of ADAM17 is associated with severe multiorgan dysfunction

Robert H J Bandsma et al. Hum Pathol. 2015 Jun.

Abstract

ADAM metallopeptidase domain 17 (ADAM17) is responsible for processing large numbers of proteins. Recently, 1 family involving 2 patients with a homozygous mutation in ADAM17 were described, presenting with skin lesions and diarrhea. In this report, we describe a second family confirming the existence of this syndrome. The proband presented with severe diarrhea, skin rash, and recurrent sepsis, eventually leading to her death at the age of 10 months. We performed exome sequencing and detailed pathological and immunological investigations. We identified a novel homozygous frameshift mutation in ADAM17 (NM_003183.4:c.308dupA) leading to a premature stop codon. CD4(+) and CD8(+) T-cell stimulation assays showed severely diminished tumor necrosis factor-α and interleukin-2 production. Skin biopsies indicated a focal neutrophilic infiltrate and spongiotic dermatitis. Interestingly, the patient developed unexplained systolic hypertension and nonspecific hepatitis with apoptosis. This report provides evidence for an important role of ADAM17 in human immunological response and underscores its multiorgan involvement.

Keywords: ADAM17; Congenital enteropathy; Exome sequencing; Immunodeficiency; Inflammation.

A, Hematoxylin and eosin stain of a skin biopsy taken from an affected scaly area on the abdomen revealing marked parakeratosis, neutrophils, and spongiosis (arrow). B, Hematoxylin and eosin stain of a duodenal biopsy obtained at 6 months of age. Duodenal biopsy shows focal villous atrophy and minimal crypt hyperplasia. C, Hematoxylin and eosin stain of a liver biopsy showing mild lymphocytic infiltrate (filled arrows), hepatocellular cholestasis (horizontal open arrow), and foci of apoptotic activity (vertical open arrows).

Representative flow cytometry analysis of TNF-α production in the CD3+CD8+ T lymphocytes of the patient (A and B) and a healthy control (C). PBMCs were in vitro stimulated with medium only (A) or PHA (B and C) and stained for CD69 and TNF-α expression. Results show a higher percentage of TNF-α–producing cells in the healthy control subject (2.5%) compared to the patient (0.4%) upon stimulation with PHA.
