“…The cMIY-1, cMIY-2 and cMIY-3 clones were contained full length cDNA inserts of 1523bp, 1385bp and 1466bp in length, respectively. Nucleotide sequences of the cDNA clones revealed that cMIY-1 was corresponded to A*2603, which was recently reported by Ishikawa et al (14), and cMIY-2 and cMIY-3 were identical with A*2601 ( Table 1) (15,16,17).…”

“…Two B62-, two B'75V-, one B15N-, one B71-, and one B77positive sample was subjected to the cloning of cDNA and the determination of nucleotide sequence. The strategies of cloning and sequencing were described previously (21,22). Three new B15 variants were subjected to direct sequencing, because only genomic DNAs were available.…”

In order to further clarify the diversity of the HLA-B15 antigens and the correspondence of serological types with alleles in Asians, we screened various B15 serological splits by means of a polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) method. Subsequently, the genes encoding various B15 variants were sequenced. Two novel alleles, B*1528 and B*1529, were identified: the nucleotide sequence of the former contained a single-base substitution at position 263 in exon 2 as compared to that of the B*1501 allele, which results in an amino acid change at position 64 in the alpha 1 domain, and the nucleotide sequence of the latter differs from that of B*1518 by a single-base substitution at position 272 of exon 2 which results in an amino acid change at position 67 of the alpha 1 domain. One new allele, B*1521, described recently in Australian Aborigines was also identified in Asians in the present study. Moreover, the results of sequencing demonstrated that Asian HLA-B62, B70, and B77 antigens are encoded by B*1501, B*1518, and B*1513, respectively. Two splits of B75 antigens, B75V (TS-1) and B15N, which have been proposed to exist in the Japanese population were encoded by B*1511 and B*1502, respectively. Most of the B15 alleles detected in the present study showed positive associations with other locus antigens. Especially, B*1502 was strongly associated with Cw8, while B*1521 was strongly associated with A34 and Cw6.

“…All of the samples were obtained from unrelated Japanese individuals who have been typed by local qualified antisera. Preparation of cDNA was described previously (9,10). In brief, total RNAs were extracted from 10 ml peripheral blood by the acid-guanidium-phenolchloroform method, wherein the first-strand cDNA was synthesized with M-MLV (Moloney's murine leukemia virus) reverse transcriptase (BRL, Gaithersburg, MD) and random hexadeoxynucleotide mixture primers.…”

Sequence analysis of serological HLA‐A11 split antigens, A11.1 and A11.2

et al. 1994

HLA‐A11 has two serologically‐defined splits, A11.1 and A11.2, and two alleles coding for HLA‐A11, A*1101 and A*1102, have been published so far. In order to understand the relationship between the serological subtypes and the amino acid sequences, we have sequenced the alleles coding for A11.1 and A11.2. The results demonstrated that A11.1 split antigen is encoded by A*1101 and A11.2 split antigen is encoded by A*1102. Moreover, we obtained the sequences of exons 1, 5, 6, 7, and 8 of A*1102, which were not reported previously. In addition, we could distinguish A*1101 from A*1102 using a PCR‐SSCP method, confirming that A11.1 carried by different HLA haplotypes has the same sequence.
