Only the single nucleotide polymorphisms present in the coding region of the gene are represented.
ºAlleles coding for documented or predicted reduced enzyme activity;
*2: Two-fold higher KM for paclitaxel transformation [17];
*3: 15% of *1-associated turnover number [17];
*5: Expected to be an inactive gene [18];
*7: No in vitro detectable activity [21];
*8: In vitro enzyme activity 10% of the wild-type [21];
P404A: Reduced protein expression leading to decreased Vmax/KM
[32].
