For the RHD promoter and the RHD cDNA, the positions refer to the distance from A of the start codon. For introns, they refer to the distance from the intron/exon junction. For all other sequences, including SMP1 cDNA, they refer to the distance from the start of the published sequences. The mismatches in primers rey14b, rnb31, and sf3 were inadvertently introduced. Primers re11d, re014, and re04 do not exactly match dJ469D22 because they were designed from our raw sequences covering the 5′ flanking region of RHD.
