TLDR
Most cases of familial incontinentia pigmenti are due to mutations of this locus and that a new genomic rearrangement accounts for 80% of new mutations, which means that NF-κB activation is defective in IP cells.Abstract:
Familial incontinentia pigmenti (IP; MIM 308310) is a genodermatosis that segregates as an X-linked dominant disorder and is usually lethal prenatally in males. In affected females it causes highly variable abnormalities of the skin, hair, nails, teeth, eyes and central nervous system. The prominent skin signs occur in four classic cutaneous stages: perinatal inflammatory vesicles, verrucous patches, a distinctive pattern of hyperpigmentation and dermal scarring. Cells expressing the mutated X chromosome are eliminated selectively around the time of birth, so females with IP exhibit extremely skewed X-inactivation. The reasons for cell death in females and in utero lethality in males are unknown. The locus for IP has been linked genetically to the factor VIII gene in Xq28 (ref. 3). The gene for NEMO (NF-kappaB essential modulator)/IKKgamma (IkappaB kinase-gamma) has been mapped to a position 200 kilobases proximal to the factor VIII locus. NEMO is required for the activation of the transcription factor NF-kappaB and is therefore central to many immune, inflammatory and apoptotic pathways. Here we show that most cases of IP are due to mutations of this locus and that a new genomic rearrangement accounts for 80% of new mutations. As a consequence, NF-kappaB activation is defective in IP cells.read more

TL;DR: A hitherto unreported disease mechanism (defective linear ubiquitination) in patients with IP is identified and identified as a novel splice mutation in IKBKG resulting in an inactive truncated form of NEMO.

Pathogenic insights from genetic causes of autoinflammatory inflammasomopathies and interferonopathies
TL;DR: In this article , a review provides insights into the pathogenesis and genetic causes of these "prototypic" diseases caused by gain-of-function mutations in IL-1-activating inflammasomes (inflammasomopathies) and in interferonactivating pathways (interferonopathies), including STING-associated vasculopathy with onset in infancy, Aicardi-Goutieres syndrome, and proteasome-associated autoinflammatory syndromes that link activation of the viral sensors STING, "self" nucleic acid metabolism, and the ubiquitin-proteasome system to human diseases.

Embryonic lethality and liver degeneration in mice lacking the RelA component of NF-kappa B.
TL;DR: Results indicate that RelA controls inducible, but not basal, transcription in NF-κB-regulated pathways, and suggest that tumour necrosis factor-mediated induction of messenger RNAs for IκBα and granulocyte/macrophage colony stimulating factor (GM-CSF) is defective, although basal levels of these transcripts are unaltered.

TL;DR: It is demonstrated that unlike the respective single knockout mice, the p50/p52 double knockout mice fail to generate mature osteoclasts and B cells, apparently because of defects that track with these lineages in adoptive transfer experiments.
