Hybrid allele encompassing at least one RHCE exon:
RHD-RHcE(4-5)-RHD
Comments on the molecular basis:
- molecular analysis initially erroneously interpreted as deletion of exons 4 to 6
- same samples initially interpreted as "deletion type" are demonstrated to be hybrid alleles
- demonstrates Proline 226 on RHD hybrid allele
- demonstrates Proline 226 on hybrid allele
- molecular basis deduced by authors from the results of cDNA analysis
- PCR pattern, exons 3, 4, 5, 6, 7 and 9
