RHD*03.02 - RHD*DIIIb
(ISBT table: RHD partial D v5.0)
This entry is an hybrid RHD allele.
DIIIb, DIIIb Caucasian, DIIIb(Ma.) (obsolete), DIIIb(Mon.) (obsolete), RHD(I60L,S68N,S103P), RHD(V50V,I60L,S67S,S68N,S103P), RHD*150C,178C,201A,203A,307C, RHD*150C,178C,201A,203A,307C (DIIIb Caucasian), RHD*150T>C,178A>C,201G>A,203G>A,307T>C, RHD-RHCE(2)-RHD, listed as RHD-CE(2)-D, weak D type 74 (obsolete),
Molecular data
Nucleotides:
150T>C; 178A>C; 201G>A; 203G>A; 307T>C;
Amino acids: V50V; I60L; S67S; S68N; S103P;
Hybrid allele encompassing at least one RHCE exon:
RHD-RHCE(2)-RHD
Comments on the molecular basis:
- see also "Additional comments" section on the RhesusBase http://www.rhesusbase.info/RHDRHD-RHCE(2)-RHD.htm
- "exon 2 of RHD did not amplify"
- this structure is probably not the historicaly defined phenotypic DIIIb
