Hybrid allele encompassing at least one RHCE exon:
RHD-RHCe(5-7)-RHD , RHD-RHCe(5-8)-RHD,
Comments on the molecular basis:
- It was not determined whether exon 8 was derived from RHD or RHCE
- Proband 8 was genotyped in
8652401 , data included relates to this sample; the other samples were determined by their serologic reactivity profile - PCR pattern, exons 3, 4, 5, 6, 7 and 9
Extracellular position of one or more amino acid substitutions:
