The T (minor) allele is associated with:

  • Females carrying the T variant had a 32% lower ability to convert Beta-carotene. (R)
  • rs7501331(T)+ rs12934922(T)= 69% lower conversion of Beta-carotene to retinyl esters... The BCMO1 gene (rs12934922and rs7501331) is known to influence the conversion of beta-carotene to vitamin A . (R)
  • TT= 57% reduced conversion activity of beta-carotene (In test tubes) (R).
