摘要:"Objective Diagnostic pitfalls often arise in the community because of potentially misleading similarities between juvenile idiopathic arthritis (JIA) and Blau syndrome, an immune-related disorder caused by NOD2 gene mutations. It remains unclear in which population and to what extent next-generation sequencing techniques can aid in diagnosis.Methods We evaluated clinical usefulness of targeted next-generation sequencing in previously diagnosed JIA. Participants were required to have symptoms and signs suspected of Blau syndrome, including at least uveitis or cutaneous lesions in addition to arthritis. Targeted sequencing was conducted on NOD2 gene to detect diagnostic variants classified as pathogenic or likely pathogenic for Blau syndrome. We assessed the molecular diagnostic yield and clinical implications for patient care.Results Between 1 May 2008 and 1 June 2021, sequencing data were accrued from 123 previously diagnosed JIA (median age: 5 years; female: 62.6%). Targeted NOD2 sequencing yielded a positive molecular diagnosis of Blau syndrome in 21.1% (95% CI: 14.9%, 29.2%), encompassing six heterozygous missense mutations classified as pathogenic variants. Among those receiving a molecular diagnosis, changes in clinical management and treatment were considered as having occurred in 38.5%. Nine predictors were identified as being associated with a higher diagnostic yield, providing clinical clues to suspect the possibility of Blau syndrome.Conclusion Among some patients with paediatric-onset arthritis complicated with uveitis or cutaneous lesions, reassessment of the diagnosis of JIA may be warranted. Targeted NOD2 sequencing established the molecular diagnosis of Blau syndrome in nearly one-fifth of these cases and provided clinically relevant information for patient-care decisions."
