Purpose: Blau syndrome is a rare autosomal dominant disorder characterized by early onset granulomatous arthritis, uveitis, skin rash and camptodactyly. We report a familial case of Blau syndrome associated with a CARD15/NOD2 mutation.
Methods: PCR amplification and automated DNA sequencing of the complete CARD15/NOD2 coding sequence was performed.
Results: Molecular analysis in affected subjects disclosed a heterozygous c.1147G>C point mutation in CARD15/NOD2 exon 4, that predicts a p.E383K change at the protein level.
Conclusions: Blau syndrome should be considered in the differential diagnosis of childhood uveitis and the genetic analysis of the CARD15/NOD2 gene is helpful in the diagnosis.

Article Synopsis
- Yao syndrome (YAOS) is an autoinflammatory disease linked to specific genetic variants, with this study analyzing a large group of adult patients diagnosed with related conditions.
- Out of 194 patients studied, 152 were diagnosed with YAOS, while the remainder had mixed autoinflammatory diseases, often showing multiple genetic variants.
- The findings highlight the diverse presentations of YAOS and aim to increase awareness and understanding of this often underrecognized disease among healthcare professionals.

Article Synopsis
- XIAP is a protein that helps regulate cell survival and inflammation, and targeting it could benefit diseases like Crohn's disease and sarcoidosis.
- Researchers developed selective inhibitors for a specific part of XIAP (XIAP-BIR2) to disrupt its interaction with RIPK2, which is relevant to inflammatory diseases.
- They created a library of small synthetic molecules, identifying compound 20c, which effectively blocks the NOD1/2 signaling pathway in cells and holds potential as an anti-inflammatory treatment.

Human endogenous retroviruses (HERVs) are remnants of ancient retroviral infections that, over millions of years, became integrated into the human genome. While normally inactive, environmental stimuli such as infections have contributed to the transcriptional reactivation of HERV-promoting pathological conditions, including the development of autoimmunity, neurodegenerative disease and cancer. What infections trigger HERV activation? subspecies (MAP) is a pluripotent driver of human disease.
