Abstract
Three new HLA-C alleles were identified by sequence-based typing method (SBT) in 1100 participants in the Saudi Bone Marrow Donor Registry (SBMDR). HLA-C∗14:02:13 differs from HLA-C∗14:02:01G by a silent G to A substitution at nucleotide position 400 in exon 2, where lysine at position 66 remains unchanged. HLA-C∗15:72 differs from HLA-C∗15:22 by a non-synonymous C to A substitution at nucleotide position 796 in exon 3, resulting in an amino acid change from phenylalanine to leucine at position 116. HLA-C∗15:74 differs from HLA-C∗15:08 by non-synonymous C to T substitution at nucleotide position 914 in exon 3, resulting in an amino acid change from arginine to tryptophan at position 156.
