Genes affected
SLC14A1 (HGNC:10918): (solute carrier family 14 member 1 (Kidd blood group)) The protein encoded by this gene is a membrane transporter that mediates urea transport in erythrocytes. This gene forms the basis for the Kidd blood group system. [provided by RefSeq, Mar 2009]

Submissions by phenotype

BLOOD GROUP--KIDD SYSTEM Uncertain:1
Uncertain significance, no assertion criteria providedresearchAustralian Red Cross Blood Service-serology was JK:-3 (supported by UREA lysis test resistance). Sequencing showed sample was homozygous for JK:2 determining snp and heterozygous for c.342-1G>A which is known to cause JK:-3 phenotype. The additional presence of c.510delA at a heterozygous level supports that c.510delA also causes JK:-3 phenotype. This is therefore an apparent compound heterozygote giving rise to JK:-3. -
