Abstract
Background: HOIP is the catalytic subunit of the linear ubiquitination chain assembly complex (LUBAC) that is essential for NF-κB signaling and thus proper innate and adaptive immunity. To date only one patient with HOIP deficiency has been reported with clinical characteristics that include autoinflammation, immunodeficiency, amylopectinosis, and systemic lymphangiectasia. Case: We sought to identify a genetic cause of a disease for an 8 year-old girl who presented with early-onset immune deficiency and autoinflammation. Methods: Targeted next generation sequencing of 352 immune-related genes was performed. Functional studies included transcriptome analysis, cytokine profiling, and protein analysis in patients' primary cells. Results: We identified biallelic variants in close proximity to splice sites (c.1197G>C and c.1737+3A>G) in the RNF31 gene. RNA extracted from patient cells showed alternatively spliced transcripts not present in control cells. Protein expression of HOIP and LUBAC was reduced in primary cells as shown by western blotting. Patient-derived fibroblasts demonstrated attenuated IL-6 production, while PBMCs showed higher TNF production after stimulation with proinflammatory cytokines. RNA sequencing of whole blood RNA and PBMCs demonstrated a marked transcriptome wide change including differential expression of type I interferon regulated genes. Conclusion: We report the second case of HOIP deficiency with novel compound heterozygous mutations in RNF31 and distinct clinical and molecular features. Our results expand on the clinical spectrum of HOIP deficiency and molecular signatures associated with LUBAC deficiency.

Abstract
The linear ubiquitin chain assembly complex (LUBAC), composed of heme-oxidized IRP2 ubiquitin ligase 1 (HOIL1), HOIL1-interacting protein (HOIP), and SHANK-associated RH domain-interacting protein (SHARPIN), is a crucial regulator of multiple immune signaling pathways. In humans, HOIL1 or HOIP deficiency is associated with an immune disorder involving autoinflammation, immunodeficiency, and inflammatory bowel disease (IBD)-like symptoms. During viral infection, LUBAC is reported to inhibit the induction of interferon (IFN) by the cytosolic RNA sensor retinoic acid-inducible gene I (RIG-I). Surprisingly, we found that HOIL1 is essential for the induction of both type I and type III IFNs, as well as the phosphorylation of IFN regulatory factor 3 (IRF3), during murine norovirus (MNoV) infection in cultured dendritic cells. The RIG-I-like receptor, melanoma differentiation-associated protein 5 (MDA5), is also required for IFN induction and IRF3 phosphorylation during MNoV infection. Furthermore, HOIL1 and MDA5 were required for IFN induction after Theiler's murine encephalomyelitis virus infection and poly(I·C) transfection, but not Sendai virus or vesicular stomatitis virus infection, indicating that HOIL1 and LUBAC are required selectively for MDA5 signaling. Moreover, Hoil1 - / - mice exhibited defective control of acute and persistent murine norovirus infection and defective regulation of MNoV persistence by the microbiome as also observed previously for mice deficient in interferon lambda (IFN-λ) receptor, signal transducer and activator of transcription factor 1 (STAT1), and IRF3. These data indicate that LUBAC plays a critical role in IFN induction to control RNA viruses sensed by MDA5.IMPORTANCE Human noroviruses are a leading cause of gastroenteritis throughout the world but are challenging to study in vivo and in vitro Murine norovirus (MNoV) provides a tractable genetic and small-animal model to study norovirus biology and immune responses. Interferons are critical mediators of antiviral immunity, but excessive expression can dysregulate the immune system. IFN-λ plays an important role at mucosal surfaces, including the gastrointestinal tract, and both IFN-λ and commensal enteric bacteria are important modulators of persistent MNoV infection. LUBAC, of which HOIL1 is a component, is reported to inhibit type I IFN induction after RIG-I stimulation. We show, in contrast, that HOIL1 is critical for type I and III IFN induction during infection with MNoV, a virus that preferentially activates MDA5. Moreover, HOIL1 regulates MNoV infection in vivo These data reveal distinct functions for LUBAC in these closely related signaling pathways and in modulation of IFN expression.
