Anti‐K13 and the K:‐13 Phenotype

Authors:

Abstract
A ‘new’ antibody that recognizes a high‐frequency red‐cell antigen in the Kell blood group system has been found in the serum of a K–k+, Kp(a–b+), Js(a–b+) person, who is heterozygous for the silent Ko gene. The antibody, named anti‐K13, reacted with all of 1,000 unselected blood samples, but does not react with the red cells of the propositus, one of his five siblings, nor with Ko cells. Red cells of a child with chronic granulomatous disease and the McLeod phenotype were weakly reactive.
