TA repeat: Historically in the literature and at the UGT nomenclature website, the TA repeat is referred to as TA(6) for *1, TA(7) for *28, TA(5) for *36, etc. The UGT allele nomenclature website (https://www.pharmacogenomics.pha.ulaval.ca/wp-content/uploads/2015/04/UGT1A1-allele-nomenclature.html) defines them in more detail as for example: A(TA)6TAA to A(TA)7TAA for *28 and A(TA)6TAA to A(TA)5TAA for *36. Note that after the repeat and number, there is an additional TA listed in the flanking sequence as "TAA". Similar nomenclature/representation is in cell C2 of the table on the "Alleles" tab as historical referencing ("CA" in front as an anchor for the point in the sequence that the TA repeats are starting from). Rows 4 and 5 align with the indicated reference sequences. In cells C4 and C5, when counting from the first TA at the given position in the sequence and including the last TA, the 5, 6, 7, 8 repeats become 6, 7, 8, 9 because there are actually 6 to 9 "TA" repeats in the genomic and gene reference sequences.
