RHD*01EL.13 - RHD*DEL13
(ISBT table: Weak D and Del v5.0)
This entry is an RHD allele.
RHD(786delA), RHD*786delA, RHD*786delA (DEL13),
Molecular data
Nucleotides:
785del1;
Amino acids: K264Rfs*24;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
Extracellular position of one or more amino acid substitutions:
- No RhD protein is expected to be produced. However a DEL or D positive phenotype has been reported (see Phenotype section), implying the contrary. The resulting antigen may have an altered conformation.
Splicing:
Unconventional prediction methods:
Phenotype
Main D phenotype: D negative or DEL (last update: May 19, 2020)Reports by D phenotype
Other RH phenotypes: RH:-3,
