(ISBT table: not listed)
This entry is an RHD allele.
RHD*634+5A, RHD*634+5A (IVS4+5A), RHD*634+5G>A, weak D type 82 (obsolete), weak RHD(IVS4+5G>A),
Molecular data
Nucleotides:
intronic 634G>A;
Amino acids: 0;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
Extracellular position of one or more amino acid substitutions:
- Silent or intronic mutations: none of the mutations are predicted to affect an extracellular amino acid.
Splicing:
