Yang EKL, Marsh SGE, Chen PY, Chen CP, Chen SP, Lin PY. A dispermic chimerism detected in a Taiwanese potential unrelated hematopoietic stem cell donor. HLA 2017; 89:98-103. [PMID: 28102039 DOI: 10.1111/tan.12954] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Revised: 11/08/2016] [Accepted: 12/09/2016] [Indexed: 01/07/2023]
Abstract
Chimerism is defined as the presence of 2 or more than 1 genetically distinct cell populations in an organism. Dispermic chimeras are derived from the fertilization of 1 or 2 matured nuclei by 2 sperms. We here report detection of a healthy and phenotypically normal female with normal ABO red blood cell typing in whom dispermic chimerism was suspected after 3 alleles were identified at multiple human leukocyte antigen (HLA) loci using molecular HLA analysis. Molecular HLA typing showed the donor to have 3 HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1 alleles in blood, saliva and nail samples. In addition, 3 of her 9 short tandem repeat loci also showed to have 3 distinct alleles in blood, nail and saliva specimens. In all investigations, the third alleles were attributed to a dual paternal contribution. This case represents a dispermic chimerism, with 2 paternal and 1 maternal haplotypes variably distributed throughout body tissues in a healthy and phenotypically normal female without abnormalities in erythrocyte ABO blood group. The origin of this chimerism is probably due to the fertilization of a single egg and its polar body, or a parthenogenetic egg, by 2 sperms.

Yang KL, Zheng ZZ. HLA haplotype in association with the low incidence C*07:66 allele found by case analysis of Taiwanese and mainland Chinese individuals. Tzu Chi Med J 2016; 28:139-142. [PMID: 28757744 PMCID: PMC5442898 DOI: 10.1016/j.tcmj.2016.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2016] [Revised: 09/05/2016] [Accepted: 09/19/2016] [Indexed: 01/24/2023] Open
Abstract
Objectives: HLA-C*07:66 is a low-incidence HLA-C allele. The aim of the study is to report the Taiwanese and mainland Chinese ethnicities of individuals with C*07:66, together with its uniqueness and polymorphism. Materials and Methods: A sequence-based typing method was employed to confirm this low-incidence allele. Polymerase chain reaction was performed to amplify exons 2, 3, and 4 of the HLA-A, HLA-B, and HLA-C loci and exon 2 of the HLA-DRB1 and HLA-DQB1 loci using group-specific primer sets. The amplicons were sequenced in both directions using BigDye Terminator Cycle Sequencing Ready Reaction kit. The blood donors in this study consisted of randomized Taiwanese and mainland Chinese individuals and family members with the C*07:66 allele. Results: The DNA sequence of C*07:66 is identical to that of C*07:02:01:01 for exons 2, 3, and 4, except for residue 688 in exon 4. This nucleotide substitution causes a single amino acid alteration to the protein sequence of C*07:02:01:01. Confirmation of the DNA and protein sequences of C*07:66 and the Taiwanese and mainland Chinese ethnicities of individuals with this allele were established in this study. One probable HLA C*07:66-associated HLA haplotype may be deduced from these individuals. Conclusion: The information on the ethnicity of the C*07:66 allele and the deduced probable HLA haplotype associated with the low-incidence C*07:66 allele reported in this study may aid in HLA testing laboratories for reference purposes. In addition, they can be used by stem cell transplant donor search coordinators to help create, for patients bearing this uncommon HLA allele, strategies for finding compatible donors using bone marrow donor registries comprising unrelated individuals.

Abstract
Objective: HLA-C*04:82 is a low incidence HLA-C allele. The aim here is to report the ethnicity of C*04:82 and its associated HLA haplotypes among Taiwanese individuals. Materials and Methods: A sequence-based typing method was used to confirm this low incidence allele. Polymerase chain reaction was performed to amplify exons 2 and 3 of the HLA-A, HLA-B, and HLA-C loci and exon 2 of the HLA-DRB1 locus using group-specific primer sets. The amplicons were sequenced in both directions using Terminator Cycle Sequencing Ready Reaction kits and the manufacturer's protocols. The potential unrelated bone marrow stem cell donors in this study were randomized individuals with Taiwanese ethnicity who participated in the Tzu Chi Bone Marrow Donor Registry. The family members in the family part of the study were volunteer blood donors. Results: The DNA sequence of C*04:82 was identical to C*04:01:01:01 in exons 2, 3, and 4. It differed from C*04:01:01:01 in exon 5 where a segment of nucleotides (CTAGCTGTC) was inserted between residues 969 and 970 of C*04:01:01:01. The insertion of these nucleotides caused a 35 amino acid alteration to the protein sequence of C*04:01:01:01. Three probable HLA haplotypes that were associated with C*04:82 among Taiwanese individuals were deduced. Confirmation of the DNA and protein sequences of C*04:82 and its Taiwanese ethnicity were established in this study. Conclusion: The ethnicity of the C*04:82 allele and the deduced probable HLA haplotypes associated with the low-incidence C*04:82 allele are of value for reference purposes for HLA testing laboratories. In addition, they can be used by search coordinators to aid the creation of a strategy for finding compatible stem cell donors for patients who carry this uncommon HLA allele.

Yang KL. Deduced probable HLA-C*07:359-associated human leukocyte antigen haplotypes found by case analysis of Taiwanese unrelated bone marrow hematopoietic stem cell donors. Tzu Chi Med J 2016; 28:59-62. [PMID: 28757723 PMCID: PMC5442894 DOI: 10.1016/j.tcmj.2016.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Revised: 03/14/2016] [Accepted: 03/18/2016] [Indexed: 11/14/2022] Open
Abstract
Objectives: HLA-C*07:359 is a low-incidence allele in the human leukocyte antigen (HLA)-C locus. The objective of this study is to report the ethnicity and haplotypes of HLA-C*07:359 that were found during an analysis of Taiwanese unrelated bone marrow hematopoietic stem cell donors. Materials and methods: A sequence-based typing method was employed to confirm low-incidence al-leles. Polymerase chain reaction was performed to amplify exon 2 and exon 3 of the HLA-A, HLA-B, and HLA-C loci, as well as exon 2 of the HLA-DRB1 locus, using group-specific primer sets. The amplicons were sequenced in both directions using BigDye Terminator Cycle Sequencing Ready Reaction kits, according to the manufacturer's protocols. The potential unrelated bone marrow stem cell donors investigated here are individuals with Taiwanese ethnicity who are participating in the Tzu Chi Bone Marrow Donor Registry. Results: The DNA sequence of C*07:359 is identical to that of C*07:02:01:01 in exons 2, 3, and 4 except at residue 862, where the G of C*07:02:01:01 is substituted by the A of C*07:359. The nucleotide exchange leads to an amino acid replacement at codon 264, where the glutamic acid of C*07:02:01:01 is replaced by the lysine of C*07:359. We deduced a probable HLA-B and HLA-C haplotype that is associated with C*07:359 in Taiwanese, namely B*39-C*07:359. Conclusion: Information on the ethnicity of the C*07:359 allele and its deduced probable HLA haplotypes that are associated with the low-incidence C*07:359 allele reported here are of value to HLA testing laboratories for reference purposes. In addition, they can be used by stem cell transplantation donor search coordinators to determine a strategy for finding compatible donors using unrelated bone marrow donor registries when patients carry this uncommon HLA allele.

Abstract
We report here a novel variant of HLA-DRB1*10, DRB1*10:04, discovered in a Taiwanese volunteer bone marrow donor by a sequence-based typing (SBT) method. The DNA sequence of DRB1*10:04 differs from DRB1*10:01:01, in exon 2, at nucleotide positions 296 (G fi A) and 303 (T fi G). The nucleotide changes caused an amino acid substitution at amino acid residue 70 (R fi Q). We hypothesize that the formation of DRB1*10:04 was probably the result of a gene recombination event where DRB1*10:01:01 received a minimum length of DNA sequence from DRB1*04:05:01, as the sequence of DRB1*10:04 is identical to DRB1*10:01:01 in exon 2 except the sequence from nucleotide 296 to nucleotide 303, which is identical to DRB1*04:05:01. The plausible HLA-A, -B, -C and - DRB1 haplotypes in association with DRB1*10:04 was deduced as A*01:01-B*37:01-C*06:02-DRB1*10:04.

Abstract
We detected a rare HLA-B locus allele, B*39:77, in a Taiwanese unrelated marrow stem cell donor in our routine HLA sequence-based typing (SBT) exercise for a possible haematopoietic stem cell donation. In exons 2, 3 and 4, the DNA sequence of B*39:77 is identical to the sequence of B*39:01:01:01 except one nucleotide at nucleotide position 733 (G->A) in exon 4. The nucleotide variation caused one amino acid alteration at residue 221 (Gly->Ser). B*39:77 was probably derived from a nucleotide substitution event involving B*39:01:01:01. The probable HLA-A, -B, -C, -DRB1 and -DQB1 haplotype in association with B*39:77 may be deduced as A*02:01-B*39:77-C*07:02-DRB1*08:03-DQB1*06:01. Our discovery of B*39:77 in Taiwanese adds further polymorphism of B*39 variants in Taiwanese population.

Abstract
Using DNA sequence-based typing method, we found a new HLA-B*40 variant, B*40:221, in a Taiwanese hematopoietic stem cell donor. The allele sequence of B*40:221 is identical to the sequence of B*40:01:01 in exons 2, 3 and 4 except the nucleotides at codon 265 (GGG→AGG). The sequence variation caused one amino acid exchange at residue 265 where Gly was replaced by Arg. The probable HLA-A, -B, -C, -DRB1 and -DQB1 haplotype in association with B*40:221 may be deduced as HLA-A*11:01-B*40:221-C*03:04-DRB1*14:54-DQB1*05:02. The generation of B*40:221 is thought as a result of a nucleotide point mutation involving B*40:01:01. Our discovery of B*40:221 increases the polymorphism of B*40 in Taiwanese.

Abstract
The allele HLA-DRB1*03:20, a variant of DRB1*03, was first reported to the IMGT HLA database in April 2001 without indication on the ethnicity of the blood donor (Cell ID: HC 125775). We found a Taiwanese volunteer hematopoietic stem cell donor carries DRB1*03:20 by a sequence-based typing (SBT) method. The DNA sequence of DRB1*03:20 is identical to the sequence of DRB1*03:01:01 in exon 2, except a nucleotide substitution at position 341(T→C) (GTT→GCT at codon 85). The nucleotide replacement produced an amino acid variation at residue 85 (V→A). We hypothesize that DRB1*03:20 was probably derived from DRB1*03:01:01 via a nucleotide point mutation event. The probable HLA haplotype in association with DRB1*03:20 was deduced as A*11:02-B*58:01-C*07:02-DRB1*03:20. We here report the Taiwanese/Chinese ethnicity of DRB1*03:20.

The DNA sequence of B*13:02:13 is identical to the sequence of B*13:02:01 in exons 2 and 3 except the nucleotide at position 588 where G is replaced by T (codon 172; CTG→CTT). The DNA sequence variation did not alter the amino acid sequence of B*13:02:01. The generation of B*13:02:13 is thought to derive from B*13:02:01 as a result of a silence mutation. The probable HLA-A, HLA-B and HLA-DRB1 haplotype in association with B*13:02:1 may be deduced as HLA-A*24-B*13:02:13-DRB1*07:01 or HLA-A*02-B*13:02:13-DRB1*07:01. The discovery of B*13:02:13 furthers the polymorphism of HLA-B*13 and HLA-B*13:02.

Abstract
We detected a Caucasoid HLA-B allele, HLA-B*44:55, in a potential Taiwanese/Chinese bone marrow hematopoietic stem cell donor during our routine HLA SBT (sequence-based typing) practice. The sequence of B*44:55 varies with B*44:02:01:01 with one nucleotide in exon 2 at position 97 (T->C), while it differs from B*44:03:01 with one nucleotide in exon 2 at position 97 (T->C) and three nucleotides in exon 3 at residues 538-540 (CTG->GAC). The nucleotide replacements caused one amino acid variation with B*44:02:01:01 at residue 9 (Y->H) and two amino acid variations with B*44:03:01 at residue 9 (Y->H) and residue 156 (L->D). The formation of B*44:55 is probably the result of a nucleotide substitution involving B*44:02:01:01 at position 97 (T->C). The Taiwanese/Chinese donor with B*44:55 claims having no kinship with Caucasian. Our speculations on the origin of the Taiwanese/Chinese B*44:55 will be presented.

Abstract
We detected a rare HLA-B locus allele, B*40:97, in a Taiwanese unrelated donor in our routine HLA SBT (sequence-based typing) exercise for a possible hematopoietic stem cell donation. In exons 2, 3 and 4, the sequence of B*40:97 is identical to the sequence of B*40:02:01 except one nucleotide at nucleotide position 760 (C->T) in exon 4. The nucleotide variation caused one amino acid alteration at residue 230 (L->F). B*40:97 was probably derived from a nucleotide substitution event where C was replaced by T at nucleotide 760 involving B*40:02:01. The HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 haplotype in association with B*40:97 may be deduced as A*26:01-B*40:97-C*03:03-DRB1*11:01-DQB1*03:03. Our recognition of B*40:97 in Taiwanese helps to fill the void of ethnic information for the allele B*40:97 reported to the IMGT/HLA Database.

Abstract
We detected a rare HLA-A*24:137 allele in an unrelated Taiwanese haematopoietic stem cell donor during a routine SBT (sequence-based typing) HLA typing exercise. The DNA sequence of A*24:137 is identical to the sequence of A*24:02:01:01 in exons 2 and 3 except at codon 21 where CGC was replaced with CAA. The DNA variation caused an amino acid alteration at amino acid residue 21 (R->Q). The HLA haplotype in association with A*24:137 may be deduced as A*24:137-B*15-DRB1*14. The formation of A*24:137 was probably the result of a nucleotide point mutation involving A*24:02:01:01. It remains to be determined whether A*24:137 is restricted to Taiwanese/Chinese ethnicity.

Abstract
Using a sequence-based typing method, we found a new HLA-B*40 variant, B*40:159, in a Taiwanese hematopoietic stem cell donor. The sequence of B*40:159 is identical to the sequence of B*40:06:01:01 in exons 2 and 3 except the nucleotides at positions 412 (A → G) and 429 (A → C). The sequence variation caused two amino acid exchanges at residue 114 (N → D) and residue 116 (Y → S). The probable HLA-A, HLA-B, HLA-C and HLA-DRB1 haplotype in association with B*40:159 may be deduced as HLA-A*02:06-B*40:159-C*08:01-DRB1*08:03. The generation of B*40:159 is thought as the result of a sequence recombination event where B*46:01:01:01, B*15:01:01 or B*15:02:01 donated a minimum length of the DNA sequence from residue 412 to residue 419 to the recipient sequence of B*40:06:01:01.

Abstract
According to the IMGT/HLA Database, the DNA sequence of A*11:53 is identical to A*11:02:01 in exons 2, 3, 4 and 5 except at codon 276. A*11:53 was reported as a rare variant of A*11, while A*11:02:01 was understood to be the second most frequently observed variant of A*11 after A*11:01:01 in Taiwanese. We sequenced HLA-A locus exons 2, 3, 4 and 5 of Taiwanese blood donors (n = 50) previously typed to carry A*11:02:01. We found out all of their sequences are identical to A*11:53 in exons 2, 3, 4 and 5' part of exon 5 including codon 276.

Abstract
We have characterized the HLA-A, -B, -DRB1, -DQA1 and -DQB1 profiles of three major ethnic groups living in Chelyabinsk Region of Russian South Urals, viz., Russians (n = 207), Bashkirs (n = 146) and Tatars (n = 135). First field level typing was performed by PCR using sequence-specific primers. Estimates included carriage and gene frequencies, linkage disequilibrium and its significance and related values. Population comparisons were made between the allele family frequencies of the three populations and between these populations and 20 others using a dendrogram. Chelyabinsk Region Russians demonstrate all the features typical of a Caucasoid population, but also have some peculiarities. Together with Tatars, Russians have high frequencies of allele families and haplotypes characteristic of Finno-Ugric populations. This presupposes a Finno-Ugric impact on Russian and Tatar ethnogenesis. However, this was not apparent in Bashkirs, the first of the three populations to live in this territory, and implies admixture with populations of a Finno-Ugric origin with precursors of Russians and Tatars before they came to the South Urals. The Bashkirs appear close to Mongoloids in allele and haplotype distribution. However, Bashkirs cannot be labelled either as typical Mongoloids or as Caucasoids. Thus, Bashkirs possess some alleles and haplotypes frequent in Mongoloids, which supports the Turkic impact on Bashkir ethnogenesis, but also possess the AH 8.1 haplotype, which could evidence an ancient Caucasoid population that took part in their ethnic formation or of recent admixture with adjacent populations (Russians and Tatars). Bashkirs showed no features of populations with a substantial Finno-Ugric component, for example Chuvashes or Russian Saami. This disputes the commonly held belief of a Finno-Ugric origin for Bashkirs. Tatars appeared close to many European populations. However, they possessed some characteristics of Asiatic populations possibly reflecting a Mongoloid influence on Tatar ethnogenesis. Some aspects of HLA in Tatars appeared close to Chuvashes and Bulgarians, thus supporting the view that Tatars may be descendents of ancient Bulgars.

Abstract
Here, we report a novel human leucocyte antigen (HLA)-DRB1 allele, DRB1*03:77, discovered in a Taiwanese unrelated volunteer hematopoietic stem cell donor by a sequence-based typing (SBT) method. The DNA sequence of DRB1*03:77 is identical to the DNA sequence of DRB1*03:01:01 in exon 2 except one nucleotide at position 223 (G→C). The nucleotide substitution caused an amino acid replacement at residue 46 (E→Q). The formation of DRB1*03:77 was thought as the result of a nucleotide point mutation. The probable HLA-A, HLA-B and HLA-DRB1 haplotype in association with DRB1*03:77 may be deduced as A*33-B*58-DRB1*03:77. The donor was a Minna Taiwanese whose ancestors came from mainland China.

In exon 2, the DNA sequence of DRB1*16:16 is identical to the sequence of DRB1*16:02:01 except the nucleotides at positions 258 (C→T), 260 (C→A) and 261 (T→G). The nucleotide substitution produced an amino acid replacement at residue 58 (A→E). The formation of DRB1*16:16 was probably generated by a DNA sequence recombination event involving DRB1*11:01:01 and DRB1*16:02:01. The probable HLA-A, -B and -DRB1 haplotype in association with DRB1*16:16 may be deduced as A*02-B*38-DRB1*16:16.

The sequence of B*51:112 is identical to the sequence of B*51:01:01 in exons 2, 3 and 4, except the nucleotides at positions 206 (C→A) and 213 (C→G).

The generation of B*51:112 was probably as the result of a DNA recombination event where B*40:01:01 acted as a sequence donor donating a segment of the DNA sequence to the recipient sequence B*51:01:01. The donor carrying B*51:112 was a Minna Taiwanese whose ancestor came to Taiwan from the southern region of China.

Abstract
We report here two HLA-B*27 alleles, B*27:86 and B*27:25, found in two Taiwanese blood donors. The new sequence of B*27:86 is identical to B*27:04:01 in exons 2 and 3, except at nucleotide 602 (A → G) in exon 3. The nucleotide change caused an amino acid substitution from E to G at amino acid residue 177. The sequence of B*27:25 is identical to B*27:04:01 in exons 2, 3, 4, 5, 6 and 7 except at nucleotides 538, 539, 559 and 560 in exon 4. The nucleotide changes caused amino acid substitutions from L to W and from E to L at residues 156 and 163, respectively. The generation of B*27:86 was probably resulted by a point mutation while the generation of B*27:25 may have been derived from a sequence recombination event between B*46:01:01 and B*27:04:01. The probable HLA-A, -B and -DRB1 haplotypes in association with B*27:86 and B*27:25 may be deduced as A*11:53-B*27:86-DRB1*12 and A*11:01-B*27:25-DRB1*04:05, respectively.

Abstract
We report here two novel HLA-B alleles, B*46:13:03 and B*15:189, discovered in two Taiwanese volunteer bone marrow donors. The sequence of B*15:189 has a nucleotide sequence possibly derived from a recombination event between HLA-B*39:01:01 and B*15:01:01:01, while the origin of the sequence B*46:13:03 was less obvious to postulate, considering the low frequency of B*46:13 in the general population and the silent mutations involved. Our report here adds further HLA polymorphism to the growing lists of HLA-B*46 and HLA-B*15 and provides an additional HLA information for donor search programme for patients undergoing transplant.

Abstract
We report here an HLA-A allele, A*11:90, found in a Taiwanese cord blood sample using DNA sequence-based typing (SBT) protocol after observing an anomalous reaction pattern in a sequence-specific oligonucleotide (SSO) typing exercise. The sequence of A*11:90 is identical to A*11:01:01, the most predominant A*11 variant in Taiwanese, in exon 2 but differs from A*11:01:01 in exon 3 by two nucleotide substitutions at codon 163 (c.487C>G and c.488G>A), resulting R163E. In comparison with the sequence of A*11:02:01, the second most predominant subtype of A*11 in Taiwanese A*11:90 has one nucleotide difference at codon 19 (c.55A>G) in exon 2 resulting K19E and two nucleotides variations at codon 163 (c.487C>G and c.488G>A) in exon 3 resulting R163E. HLA-A*11:90-B*40:02-DRB1*11:01 is the deduced probable HLA haplotype in association with A*11:90. The generation of A*11:90 is thought to involve a DNA recombination event between alleles A*11:01:01 and A*80:01 where A*80:01 donated a fragment of the DNA sequence (from n.t. 487 to n.t. 497) to the recipient sequence of A*11:01:01.

The mismatched sequence segment is identical to a sequence segment of A*02:03:01, suggesting that the formation of A*26:20 was resulted from a DNA recombination event between A*26:01:01 and A*02:03:01 sequences. A*26:20 differs from A*26:01:01 with c.98A > T resulting in p.Tyr33Phe.

Abstract
HLA-B*5214, a novel rare allele of HLA-B*52 variant, was found in a Taiwanese volunteer bone marrow donor by sequence-based typing method. The sequence of B*5214 is identical to that of B*520101 in exon 2 but differs from B*520101 in exon 3 at nucleotide positions 419 A-->T and 435 A-->G. Alteration of these two nucleotides resulted an amino acid substitution at amino acid residue 116 Y-->F ( TAC-->TTC) and a silent exchange at residue 121 K-->K (AAA-->AAG).

Abstract
High-resolution human leucocyte antigen (HLA)-A, -B, -Cw, -DRB1, and -DQB1 alleles and haplotype frequencies were analysed from 718 Chinese healthy donors selected from the Chinese Marrow Donor Program registry based on HLA donor-recipient confirmatory typings. A total of 28 HLA-A, 61 HLA-B, 30 HLA-Cw, 40 HLA-DRB1 and 18 HLA-DQB1 alleles were identified, and HLA-A*1101, A*2402, A*0201, B*4001, Cw*0702, Cw*0102, Cw*0304, DRB1*0901, DRB1*1501, DQB1*0301, DQB1*0303 and DQB1*0601 were found with frequencies higher than 10% in this study population. Multiple-locus haplotype analysis by the maximum-likelihood method revealed 45 A-B, 38 Cw-B, 47 B-DRB1, 29 DRB1-DQB1, 24 A-B-DRB1, 38 A-Cw-B, 23 A-Cw-B-DRB1, 33 Cw-B-DRB1-DQB1 and 22 A-Cw-B-DRB1-DQB1 haplotypes with frequencies >0.5%. The most common two-, three-, four- and five-locus haplotypes in this population were: A*0207-B*4601 (7.34%), Cw*0102-B*4601 (8.71%), B*1302-DRB1*0701 (6.19%), DRB1*0901-DQB1*0303 (14.27%), A*3001-B*1302-DRB1*0701 (5.36%), A*0207-Cw*0102-B*4601 (7.06%), A*3001-Cw*0602-B*1302-DRB1*0701 (5.36%), Cw*0602-B*1302-DRB1*0701-DQB1*0202 (6.12%) and A*3001-Cw*0602-B*1302-DRB1*0701-DQB1*0202 (5.29%). Presentation of the high-resolution alleles and haplotypes data at HLA-A, -B, -Cw, -DRB1 and -DQB1 loci will be useful for HLA matching in transplantation as well as for other medical and anthropological applications in the Chinese population.

Abstract
Here we report the identification and sequence analysis of a new HLA-A11* variant, A*1131 allele, found in a Taiwanese volunteer bone marrow donor. The novel A*11 variant is identical to A*1125 in exon 2 but differs from A*1125 in exon 3 by one nucleotide substitution at position 527 causing an amino acid change at codon 152 E-->V (GAG-->GTG). In comparison with HLA-A*110101, allele A*1131 has three nucleotide differences in exon 3: 527 C-->T, 538 C-->T and 539 A-->T leading to two amino acid variations at residues 152 A-->V and 156 Q-->L.

Abstract
BACKGROUND AND AIMS Loss or downregulation of human leukocyte antigen (HLA) class I expression has been reported in a variety of human tumors including oral squamous cell carcinoma (OSCC). METHODS Expression of HLA class I molecules were evaluated by immunohistochemistry, flow cytometry, semi-quantitative Western blot and RT-PCR in 43 tissue samples of primary oral squamous cell carcinomas (pOSCC) from Chinese patients and two OSCC cell lines. RESULTS HLA class I heavy chain of B/C locus and A locus and beta(2-)microglobulin were obviously lost or downregulated in pOSCC with the percentage of 31, 55 and 35% respectively. The expression of HLA B/C, LMP2, LMP7, LMP10 and PA28beta in OSCC cell lines was also presumably reduced in comparison with normal epithelial cell line. CONCLUSIONS These data suggested that the downregulation of HLA class I molecules in OSCC was closely associated with the low-efficient transcription and abnormality of post-transcription regulation of HLA class I genes and antigen presentation-related genes. These results can add more light to the mechanism by which OSCC escape from immunological surveillance.

Abstract
We report here a novel HLA-B allele, B*2740, discovered in Taiwanese volunteer marrow donors. The new sequence has nucleotide variation at position 527 (T-->A) as compared to B*2708. The nucleotide change caused an amino acid substitution from valine (V) to glutamic acid (E) at codon 152. Since B*2740 carries sequence confers to HLA-Bw6 public epitope we believe that this novel B*27 allele might have been generated from a gene conversion involving a Bw4-specific allele (probably B*2704) and a Bw6-specific allele.

Abstract
Using the maximum-likelihood method with the expectation-maximization (EM) algorithm of PYPOP, high-resolution human leukocyte antigen (HLA) three-locus haplotypes (HLA-A, -B, and -C; HLA-A, -B, and -DRB1) and four-locus haplotypes (HLA-A, -B, -C, and -DRB1) were determined. Linkage disequilibrium of high-resolution HLA-B and -C alleles and HLA-DRB1 and -DQB1 alleles was also calculated. Comparison of the Taiwanese haplotypes and haplotypes from donors in the Chinese Han population, the Asia Pacific Islander ethnic category of the NMDP (National Marrow Donor Program), and the Taiwanese cord blood units demonstrated similarities and dissimilarities among the four populations. HLA allele frequencies of our study suggested that the Taiwanese have a relative population relationship with the southern Han Chinese with regard to HLA. Our results also indicated that the Taiwanese population exhibits genetic proximity with Asian Americans with regard to HLA-A and -DRB1 but not HLA-B.
