FBLIM1 and chronic recurrent multifocal osteomyelitis: Via whole-exome sequencing, a child from a consanguineous union affected by CRMO was found to harbor a rare, homozygous coding mutation in FBLIM1, and another child with CRMO was found to be a compound heterozygote for mutations in FBLIM1, with one frameshift mutation and one expression-altering enhancer mutation.
