The sequence of B51:112 is identical to the sequence of B51:01:01 in exons 2, 3 and 4, except the nucleotides at positions 206 (C→A) and 213 (C→G). The nucleotide replacement caused one amino acid substitution at residue 45 (T→K). The plausible HLA-A, -B and -DRB1 haplotype in association with B51:112 may be deduced as HLA-A02-B51:112-DRB112. The generation of B51:112 was probably as the result of a DNA recombination event where B40:01:01 acted as a sequence donor donating a segment of the DNA sequence to the recipient sequence B51:01:01. The donor carrying B51:112 was a Minna Taiwanese whose ancestor came to Taiwan from the southern region of China.
B51:112 的序列与外显子 2、3 和 4 中的 B51:01:01 序列完全相同,只有位置 206(C→A)和 213(C→G)的核苷酸发生了变化。核苷酸的替换导致第 45 位氨基酸残基(T→K)发生取代。与 B51:112 相关联的可能的 HLA-A、-B 和 -DRB1 单体型可推断为 HLA-A02-B51:112-DRB112。B51:112 的产生可能是由于 DNA 重组事件,B40:01:01 作为序列供体,将一段 DNA 序列捐赠给受体序列 B51:01:01。携带 B51:112 的供体是来自中国南方地区的台南 Minna 人。
