Erythroid urea transporter deficiency due to novel <i>JK</i>^<i>null</i> alleles

Abstract

The molecular bases of the Jk(a-b-) phenotype are diverse and this is the first report of JKnull alleles in individuals of African and subcontinental Indian descent. Although rare, these alleles should be taken into consideration when planning genotyping strategies for blood donors and patients.
