Comparative analysis of exon 10 and non-exon 10 variants in children with familial mediterranean fever: a retrospective cohort study

• This is one of the largest pediatric FMF cohorts systematically stratified into homozygous exon 10, compound heterozygous exon 10, exon 10-non-exon 10 groups, and single exon 10 allele • Exon 10-non-exon 10 variant combinations were associated with a clinically relevant inflammatory phenotype resembling compound exon 10 genotypes, suggesting a potential modifier role of non-exon 10 variants.
