A deep intronic mutation in FGB creates a consensus exonic splicing enhancer motif that results in afibrinogenemia caused by aberrant mRNA splicing, which can be corrected in vitro with antisense oligonucleotide treatment.

Abstract excerpt
We previously described a novel homozygous point mutation (FGB c.115-600A>G) located deep within intron 1 of the fibrinogen beta gene (FGB), as a likely cause of afibrinogenemia. While this was the only mutation detected, its pathological mechanism was unclear. Here we show the mutation causes the inclusion of a 50-bp cryptic exon by creating a consensus heptad motif recognized by the spliceosome recruiting...
