Figure 3From: A novel de novo mutation in the serine-threonine kinase STK11 gene in a Korean patient with Peutz-Jeghers syndrome Identification of the STK11 gene mutation. Direct sequencing of the proband demonstrated a 1-bp deletion (c.826delG) in exon 6 of the STK11 gene, resulting in a frameshift deletion mutation (p.Gly276AlafsX11). The proband's family members did not have the mutation. The localization of the deletion is indicated by the arrow.Back to article page
