  • Both the pHuman-mouse and pMouse constructs induced the expression of A and B antigens, suggesting that the mouse gene is a cis -AB gene and encodes an enzyme with both A and B transferase activity. (google.com)
  • The two major codominant alleles of the gene, JK*A and JK*B , have similar frequencies in Caucasian populations (0.51 and 0.49, respectively) and define the Jk a and Jk b antigens, respectively. (rbhh.org)
  • Absence of the XK protein (such as through genetic deletion or through a single point mutation within the coding region of the XK gene ), leads to marked reduction of the Kell antigens on the red blood cell surface. (wikipedia.org)
  • found
  • Three antigens have been found (Jk a , Jk b and Jk3) on the neighboring fourth extracellular looping and three phenotypes, Jk(a + b−), Jk(a − b+), and Jk(a + b+), are common among different populations. (rbhh.org)
  • association
  • But because of the abundance and wide distribution of ABH antigens, I will not be so surprised if in the future, the currently fashionable genome-wide association studies (GWAS) find an association between certain definable personality traits and ABO SNPs. (google.com)
  • particularly
  • This is particularly true for the "K" antigen which shows a relatively high antigenicity and moderately low frequency (~9%) in Caucasian populations. (wikipedia.org)
  • world
  • This is an excellent reference book for those of us who work in the world of blood groups, whether in research or in reference laboratories. (wiley.com)
