  • [Nausea; Vomiting]
    The G allele of this SNP is associated with increased incidence of medium-severe nausea or vomiting, and with reduced leukocyte counts in gastric carcinoma and colon carcinoma patients treated with 5-fluorouracil. The elimination constant (Ke) for 5-fluorouracil was significantly lower in patients homozygous for the G allele.
