Notes
rs1801279 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 rs1801279(A).
