SLC10A2 and gallstones: The mutational analysis of 60 gallstone carriers and 33 control individuals resulted in the identification of six novel distinct variants in the untranslated region (5′-UTR) and in the coding regions of SLC10A2. These genetic variants (two in the 5′ UTR region, two in exon 1 and two in exon 5) were found in female and in male gallstone carriers as well as in one male control.
