RHD*34 - RHD*DIM
(ISBT table: RHD partial D v5.0)
This entry is an RHD allele.
DIM, DIleM, RHD(C285Y), RHD*854A, RHD*854A (DIM, RHD*34), RHD*854G>A,
Molecular data
Nucleotides:
854G>A;
Amino acids: C285Y;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
Extracellular position of one or more amino acid substitutions:
- considered to be extracellular
- none of the mutations are predicted to affect an extracellular amino acid
