Abstract:
Background: FOXE1 is a candidate tumour suppressor gene at human chromosome locus 9q22. This is a region frequently lost in squamous cell cancer.
Objectives: To assess the influence of FOXE1 variations on genetic susceptibility to cutaneous squamous cell carcinoma (SCC).
Methods: We performed mutational analysis of FOXE1 in 320 DNA samples isolated from 60 SCC specimens, 60 adjacent histologically normal skin samples and 200 blood samples.
Results: No somatic mutations were evident. Instead the polyalanine tract showed marked variation in its length between samples from patients with SCC and normal controls.
Conclusions: These results imply that another tumour suppressor gene at this locus may be more important than FOXE1 in skin carcinogenesis and suggest that variation in the FOXE1 polyalanine tract length predisposes to cutaneous SCC.
