In this study, we investigated the association between the FasL -844T/C polymorphism and the risk of developing esophageal squamous cell carcinoma (ESCC) in South China. For the investigation, we randomly selected 248 patients suffering from ESCC from Southern China along with 297 healthy individuals as the control group. The relationship between the FasL gene -844T/C SNP and ESCC was studied using PCR-RFLP and immunohistochemistry. The Fas -1377G/A SNP was also selected for investigation to detect whether it interferes with the functional effect of the FasL -844C/T polymorphism in ESCC development. A significant difference in the FasL -844T/C genotypes between the patients and the control group was observed (P<0.05), with those expressing the C allele having a significantly reduced risk of developing ESCC, however elderly patients (>60 years) exhibited amoremalignant pathological grade if they were homozygous for the C allele. FasL -844 CC combined with the Fas -1377 G allele is a protective factor against ESCC. Having said this, even though the C allele has a protective effect prior to development of ESCC, once the host does develop the condition the tumour will develop faster and have a higher degree of malignancy than T carriers [ABSTRACT FROM AUTHOR]
