Article Description

Background: Germline mutations or large-scale deletions in the coding region and splice sites of STK11/LKB1 do not account for all cases of Peutz-Jeghers syndrome (PJS). It is conceivable that, on the basis of data from other diseases, inherited variation in promoter elements of STK11/LKB1 may cause PJS. Results: Phylogenetic foot printing and transcription factor binding site prediction of sequence 5′ to the coding sequence of STK11/LKB1 was performed to identify non-coding sequences of DNA indicative of regulatory elements. A series of 33 PJS cases in whom no mutation in STK11/LKB1 could be identified were screened for sequence changes in the putative promoter defined by nucleotides -1090 to -1472. Two novel sequence changes were identified, but were found to be present in healthy individuals. Conclusion: These findings indicate that promoter sequence changes are unlikely to contribute to PJS. © 2005 Hearle et al; licensee BioMed Central Ltd.
