To investigate STK11 gene mutation in a pedigree with Peutz-Jeghers syndrome (PJS).


A pedigree of PJS was investigated. DNA was extracted from peripheral blood samples from affected and unaffected members of the pedigree and 100 unrelated healthy controls. PCR was performed to amplify all of the 9 coding exons of STK11 gene. PCR products were directly sequenced to detect mutation.


A missense mutation p.F354L (c.1062C>G) in exon 8 of the STK11 gene has been identified in all patients with PJS, but was not found in normal individuals from the pedigree and 100 unrelated controls.


A missense mutation p.F354L of STK11 gene probably underlies the disease in this pedigree.
