Notes
rs1058396, also known as c.838G>A, p.Asp280Asn and D280N, is a variant in the SLC14A1 gene on chromosome 18 that encodes the Jk(a)/Jk(b) Kidd Blood Group antigens. The rs1058396(G) allele encodes the Asp amino acid defining the Jk(a) antigen, and the (A) allele encodes the Asn defining Jk(b). Bladder Cancer Non-ABO Blood Groups
A;A
Unless there are other mitigating mutations, this genotype leads to being Kidd blood group Jk(a-/b+).
A;G
Unless there are other mitigating mutations, this genotype leads to being Kidd blood group Jk(a+/b+).
G;G
Unless there are other mitigating mutations, this genotype leads to being Kidd blood group Jk(a+/b-).
