The Kidd blood group system consists of three common phenotypes: Jk(a+b−), Jk(a−b+) and Jk(a+b+), and one rare phenotype, Jk(a−b−). Jk a /Jk b polymorphism is associated with c.838G>A (p.Asp280Asn) in exon 9 of the JK ( SLC 14A1 ) gene, and the corresponding alleles are named JK *01 and JK *02 . The rare phenotype Jk(a−b−) was first found in a Filipina of Spanish and Chinese ancestry, and to date, several JK null alleles responsible for the Jk(a−b−) phenotype have been reported. We report seven novel JK null alleles, 4 with a JK *01 background and 3 with a JK *02 background, identified from Jk(a−b−) Japanese.
