In OMIM this TICAM1 (TRIF) is associated with {Encephalopathy, acute, infection-induced (herpes-specific), susceptibility to, 6}. OMIM reports that Sancho-Shimizu et al. (2011) (PMID: 22105173) identified causative mutations in the TRIF gene in 2 unrelated patients with herpes simplex encephalitis (HSE): a homozygous nonsense mutation (R141X) that resulted in premature termination and no detectable TRIF protein and heterozygous (S186L) substitution in the N terminus of the protein. Fibroblasts from both patients showed impaired production of IFNB, IFNL1, IFNL3 , and IL6 after stimulation with poly(I:C). Mork et al. (2015) (PMID: 26513235) report 2 unrelated Danish men (P5 and P6) with onset of herpes simplex encephalitis after age 60 years, with heterozygous missense mutations in the TICAM1 gene (A568T and S160F). Peripheral blood mononuclear cells from both patients showed variable but significantly impaired beta-interferon, CXCL10 (147310), and/or TNFA responses to poly(I;C) stimulation and/or HSV-1 infection compared to controls. There are more than 3 plausible disease causing mutations within this gene.Created: 14 Jun 2018, 3:44 p.m.

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.Created: 19 Apr 2018, 12:54 p.m.

2018-07-12 Louise Daugherty (Genomics England Curator) promoted panel to v1.0. Reviews were assessed, and panel was revised according to expert reviews and further in-house curation based on PanelApp guidelines. Previous panels (A- or hypo-gammaglobulinaemia, Congenital neutropaenia, Agranulocytosis, Combined B and T cell defect, Inherited complement deficiency and SCID panels) that were merged with this panel, were checked again for any changes/new reviews prior to versioning of this panel, these merged panels are now retired/made internal.
