A novel synonymous substitution in the GCK gene causes aberrant splicing in an Italian patient with GCK-MODY phenotype

Abstract: GCK gene analysis in an Italian MODY patient revealed a novel synonymous substitution in exon 4 (c.459T>G; p.Pro153Pro) resulting in an aberrant transcript lacking the last eight codons of the same exon. Our findings emphazise the importance of not underestimating synonymous variations when screening for disease-causing mutations. [Copyright &y& Elsevier]
