SULT1B1 and acute lymphoblastic leukemia: The SNP rs423900190 on OAR6:85,982,278 was associated with ALL and TNB, and close to this variant were found the genes SULT1B1 (sulfotransferase 1B1) and SULT1E1 (sulfotransferase 1E1), two sulfotransferases involved in the metabolism of endogenous compounds such as thyroid and steroid hormones, including estradiol inactivation (Yi et al., 2021), which play a key role in mammalian pregnancy (Bairagi et al., 2018).
