Gene: ADAM17

Provisionally associated with ?Inflammatory skin and bowel disease, neonatal, 1 #614328 (AR) in OMIM.

PMID: 22010916 - Blaydon et al 2011 - report 2 siblings with neonatal-onset inflammatory skin and bowel disease. The parents were consanguineous of Lebanese origin. One sibling died age 12 from fulminant parvovirus B19–associated myocarditis. A homozgyous 4 bp in exon 5 of ADAM17 (c.603–606delCAGA) segregated with the disease in this family; it was predicted that the mutation would introduce a frame shift and a premature stop codon (p.Asp201GlufsX11). The mutation is predicted to result in a protein that lacks all functional domains. There was reduced expression of ADAM17 in the affected brothers skin and small intestine.

PMID: 26683521 - Tsukerman et al 2015 - report a proband with consangiuneous parents with recurrent infections. He died at two years of age of respiratory failure and presumed sepsis. A homozygous deletion of exon 1 of ADAM17 was found. NK cells from the patient lacked ADAM17 protein expression. CD16 activity on the patient's NK cells is enhanced. In the study of Blaydon et al and in this study TNFα was barely secreted by the patient and in both cases this was accompanied by severe bacteremia.

PMID: 25804906 - Bandsma et al 2015 - report a proband presented with severe diarrhea, skin rash, and recurrent sepsis, eventually leading to her death at the age of 10 months. Exome sequencing 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.

PMID: 29560122 - Fuchslocher Chico et al 2018 - mouse model. ADAM17 knockout is lethal in mice, but hypomorphic ADAM17ex/ex mice have been created that express only ~5% of the original levels of ADAM17 in all tissues. These mice have increased susceptibility to dextran sulfate sodium (DSS)-induced colitis. They identify ADAM17 as a novel regulator of necroptosis.

Summary: 3 cases plus mouse model. Green review from Zornitza Stark on the PID panel.

The mutation is found to decrease the ADAM17 function which is needed for TNF-alpha production which is needed for antiviral activity.

PMID: 11773383 Tumor Necrosis Factor Alpha Exerts Powerful Anti-Influenza Virus Effects in Lung Epithelial Cells
The mutation causes a decrease in the TNF-alpha levels which is important for comparing the Influenza virus of all types(avian, swine, and human). the antiviral effect of TNF-α was greater than that of gamma or alpha interferon.

The loss of function mutation relevance to viral infection is related to parvovirus B19 infection in the girl. No other virus susceptibility is noted.


The girl died suddenly at 12 years of age from parvovirus B19–associated myocarditis; her brother had mild cardiomyopathy
We identified a loss-of-function mutation in ADAM17, which encodes a disintegrin and metalloproteinase 17 (also called tumor necrosis factor α [TNF-α]–converting enzyme, or TACE), as the probable cause of this syndrome. Peripheral-blood mononuclear cells (PBMCs) obtained from the brother at 17 years of age showed high levels of lipopolysaccharide-induced production of interleukin-1β and interleukin-6 but impaired release of TNF-α.

Immunodeficiency caused by hypomorphic mutations in ADAM17 deficiency cause epithelial and immune dysfunction. Only one family report found an affected brother and sister from a consanguineous family of Lebanese origin with neonatal inflammatory skin and bowel disease1, PMID: 22010916 (2011). Genetic deficiency of ADAM17 has been linked to neonatal inflammatory skin and bowel disease, yet the pathogenic mechanisms remain unclear. ADAM17 is likely critical for the maintenance of mucosal epithelial barriers, as shown by the defective regeneration of intestinal epithelial cells in response to experimental colitis in hypomorphic ADAM17 animal models. There is functional/mouse model evidence to support the association, and ADAM17 is known to have a role in controlling inflammation and tissue regeneration (PMID: 21752713). The phenotype was also rescued by treatment with EGFR ligands, further supporting ADAM17 maintaining epithelial barriers by providing soluble EGFR ligands.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
