Mutations in the HNF-1 alpha gene result in maturity-onset diabetes of the young (MODY); an early-onset, dominantly inherited form of diabetes caused by pancreatic beta-cell dysfunction. Splice site mutations represent approximately 10% of reported HNF-1 alpha mutations. No studies to date have investigated the effect of splice site mutations on mRNA processing because the tissues with abundant HNF-1alpha expression (liver, pancreas, kidney and gut) are not easily accessible for analysis. This study aimed to define the pathogenic mechanism in three novel splice site mutations by analysing illegitimate transcripts.
