IFN-I Score and Rare Genetic Variants in Children with Systemic Lupus Erythematosus.

Interferon I (IFN I) signaling hyperactivation is considered one of the most important pathogenetic mechanisms in systemic lupus erythematosus (SLE). Early manifestation and more severe SLE courses in children suggest a stronger genetic influence in childhood-onset SLE (cSLE). To evaluate IFN-I score and SLE-associated genetic variants in cSLE.
