Amino acids: L121M; V127A; D128G; N152T; M169L; M170R; I172F; S182T; E193K; K198N; T201R; F223V; E233Q; V238M; V245L; S248S; G263R; K267M;
Hybrid allele encompassing at least one RHCE exon:
RHD-RHCE(3-5)-RHD
Comments on the molecular basis:
- RHD or RHCE origin of exon 2 is undeterminable because the breakpoint is located within a region identical in RHD and RHCe
- see also "Additional comments" section on the RhesusBase http://www.rhesusbase.info/RHDDVItype4.htm
