* 21 alignment positions are shown where the nucleotide/gapping (-) of the SULT1A4 region differed from that of the SULT1A3 region. Exon and intron names of the SULT1A3 gene are according to [33]. All nucleotides are numbered relative to the first nucleotide of the start codon, which has a value of +1. There was no position 'zero'. The last nucleotide of the coding sequence occurs at position +3,188. Approximately 3 kb of upstream (5' UTR) and downstream (3' UTR) nucleotides were included in the comparison.
