FOXF1 and Barrett esophagus: Although we did not identify any secondary peaks (ie, associations of SNPs with oesophageal adenocarcinoma and Barrett's oesophagus that were independent of the top hits) at genome-wide significance in the conditional association analysis of the combined meta-analysis, two loci (rs34817486 near FOXF1-AS1 [also known as FENDRR] and FOXF1, and rs62331139 near LPCAT1 and SLC6A3) showed some evidence of secondary peaks (p<10−5; appendix p 10).
