rs1799929 is a SNP in the NAT2 gene, potentially encoding a variant detoxifying protein known as an N-acetyltransferase, but which NAT2 variant depends on which other NAT2 SNPs were also inherited. See the discussion of the NAT2 gene for a more complete explanation. The risk allele for this SNP is rs1799929(T). When this SNP is indicative of carrying a NAT2*5A allele, the following may be relevant: A study (based on only 42 patients) found that women with the NAT2*5A slow genotype (which presumably means rs1799929(T;T)) had a significantly higher risk of cervical cancer compared with individuals with the NAT2*5A fast genotype (i.e. carriers of only one rs1799929(T) allele), with a reported odds ratio of 7.469 (CI: 1.6-33.3, p=0.008).
