(ISBT table: not listed)
This entry is an RHD allele.
RHD(1227G>A,149-29G>C), RHD*1227A,149-29C (IVS1-29C), RHD*1227G>A,149-29G>C, RHD*1227G>A,IVS1-29G>C, RHD*149-29C,1227A,
Molecular data
Nucleotides:
intronic 149G>C; 1227G>A;
Hybrid allele encompassing at least one RHCE exon:
no
Comments on the molecular basis:
- authors associate c.336-29G>C and RHD*01EL.32, considered to be a typo which shoule read: 149-29G>C
- Table 6; 149-29G>C is an intronic polymorphism present in all samples with R1, R0 and RZ haplotypes
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:
