RHD*33 - RHD*DWI
(ISBT table: RHD partial D v5.0)
This entry is an RHD allele.
DWI, DWLLE, RHD(M358T), RHD*1073C, RHD*1073C (DWI, RHD*33), RHD*1073T>C,
Molecular data
Nucleotides:
1073T>C;
Amino acids: M358T;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
- "the Met358 Thr exchange in DWI renders Asn356 a potential N-glycosylation site. N-glycosylation of the DWI polypeptide could affect its intracellular trafficking, RBC surface expression, folding, and antigenicity."
Extracellular position of one or more amino acid substitutions:
