Task: Question Generation
Input (English): Context: The aim of the present study was to explore the association of the functional single-nucleotide polymorphism (SNP) rs3746804 in C20orf54 with the susceptibility to esophageal squamous cell carcinoma (ESCC).', 'SNP rs3746804 in C20orf54 was detected by direct sequencing in 434 ESCC patients and 554 healthy controls from Shanxi and Henan Provinces in China, geographically a high incidence area for ESCC. The frequencies and distribution of TT, CT, and CC genotypes of SNP rs3746804 between those 2 cohorts were compared and its association with ESCC was assessed.', 'For SNP rs3746804 the genotype distribution of CT and CC in ESCC patients both significantly differed from those in healthy controls (p=0.002, 0.001, respectively), while the distribution of TT did not differ significantly between the groups (p=0.757). The ratio of T:C was high in healthy individuals and low in ESCC patients. Compared to genotype CC, both genotypes CT (odds ratio (OR)=0.63, 95% confidence interval (CI) 0.48l-0.826), and CT+TT (OR=0.654, 95% CI 0.507-0.844) were associated with significantly decreased risk for ESCC.
Answer: A close association exists between functional SNP rs3746804 in C20orf54 and susceptibility to ESCC.
Output (English): Does the functional SNP rs3746804 in C20orf54 modify susceptibility to esophageal squamous cell carcinoma?
