Comments on the molecular basis:
- breakpoints are in intron 4 and 5: "The 5 ́ breakpoint region was located in the 278-bp DNA segment between base –247 in intron 4 relative to the intron 4/exon 5 junction and the cDNA base 667 in exon 5 […] The 3 ́ breakpoint region of the gene conversion was detected in the sequence obtained for exon 5 and located in the 101-bp segment between the penultimate base of exon 5, T800, and an RHD-specific G at intron 5 position 101"
- intron 4 of RHD origin; characterization of the gene conversion of 278 bp
