Differences in reference allele frequencies between cases and controls were tested using a χ2 test. Values in boldface italic type are nominally significant P values (P<.05).
ORs refer to the variant allele. Where the frequency in patients was 0, the OR has been computed under the assumption that a single patient sample carried the variant allele.
