Molecular data
Nucleotides:
Amino acids:
Hybrid allele encompassing at least one RHCE exon:
NA
Comments on the molecular basis:
- samples were tested for RHD intron 4
- samples tested for presence of absence of RHD exon 10
- some characterized, some assumed, see RHef00446
- PCR pattern, exons 3, 4, 5, 6, 7 and 9: only exon 9 was amplified
- comparison of different approaches
- PCR to detect exons 1 and 10
Extracellular position of one or more amino acid substitutions:
