[PMID: 36502279 DOI: 10.1111/tan.14937] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 09/12/2022] [Accepted: 12/02/2022] [Indexed: 12/14/2022]
Abstract
HLA class I and class II genotypes from 947 Kazakhstani individuals of Russian origin were analyzed for investigating their most likely origin. The results were compared with similar data from other Russians (East and West), and also Worldwide populations, using standard genetic distances, neighbor-joining dendrograms, correspondence and haplotype analysis. Of the five HLA loci analyzed (HLA-A, HLA-C, HLA-B, HLA-DRB1, and HLA-DQB1) genotyped, 216 HLA alleles were identified. The most frequent alleles were A*02:01 (26.5%), B*07:02 (11.1%), C*04:01 (13.5%) and C*06:02 (12.1%), DRB1*07:01 (13.8%) and DRB1*15:01 (12.2%), and DQB1*03:01 (19.7%). Significant linkage disequilibrium was noted between all HLA pairs. DRB1*15:01 ~ DQB1*06:02 (10.5%), B*07:02 ~ C*07:02 (10.0%), B*07:02 ~ DRB1*15:01 (6.3%), and A*01:01 ~ B*08:01 (4.5%) were the most frequent two-locus haplotypes identified. Subsequent analyses showed that Kazakhstani Russians were closely related to West Russia-residing populations (Northwest Slavic, Vologda, Chelyabinsk, Moscow), East Europeans (Belarus Brest, Ukraine, Poland) and Scandinavians (Swedish, Finns), but distinct from East Russia-residing populations (Tuvians, Siberians from Chukotka, Kamchatka, and Ulchi) and East Mediterraneans (Levantines, Turks, North Macedonians, Albanians), and East Asians (Koreans, Japanese, Taiwanese, Mongolians). These results are in accordance with historical data indicating that the Russians of central Asia originate mainly from European Russia during the migratory flow of 18th and 19th centuries.

Abstract
Seronegative spondyloarthritis (SpA) are variably associated with HLA-B∗27 antigen. HLA-B∗27 negative SpA has also been reported from different parts of the world. There is paucity of data on this entity from Indian subcontinent. We studied 100 consecutively diagnosed HLA-B27 negative spondyloarthritis patients from a tertiary care center in India. Modified New York Criteria for ankylosing spondylitis (AS) and ESSG criteria for SpA were used for diagnosing patients. HLA-B∗27 typing was done by an in-house PCR-SSP technique in SpA patients to exclude B∗27 positive patients and PCR-SSOP technique was used to type 100 B∗27 negative SpA patients and 100 controls from the same ethnicity. Frequency of B∗07 was significantly increased (B∗07: % PF 54 versus 18; OR 5.348; 95% CI 2.808-10.186; P value 1.14E - 07), whereas frequency of B∗40 was significantly decreased (B∗40: % PF 17 versus 32; OR 0.435; 95% CI 0.222-0.850; P value 0.013) when compared with B∗27 negative controls. Among 100 SpA patients, 47 were undifferentiated spondyloarthritis and 33 patients were reactive arthritis patients. 40% of the patients were suffering from polyarticular arthritis, 35% had pauciarticular arthritis with knee joint, hip joint, ankle joint, and SI joint involvement. We conclude that B∗07 was significantly associated with B27 negative spondyloarthropathy from Western India and majority of B∗27 negative patients were uSpA.

Abstract
Human leukocyte antigen (HLA) class I molecules are involved in the presentation of antigenic peptides to CD8(+) cytotoxic T lymphocytes (CTLs), which is important for the development of cellular immunity during viral infections and in cancers. HLA-A2 is one of the most frequent HLA class I specificities and thus is extensively studied structurally and functionally. Since its discovery, more than 300 allelic variants of this HLA specificity have been recorded. Among the HLA-A2 allelic variants, HLA-A*02:01 is the most prevalent, hence commonly used as a model to study HLA-A2-restricted CTL responses. However, HLA-A2 alleles are unevenly distributed globally such that HLA-A2 allelic variants besides A*02:01 are expressed at considerably high frequencies in Asian and African populations. Furthermore, increasing evidence of variations in the peptide-binding repertoire and CTL responses among HLA-A2 allelic variants suggests the need to understand these differences among various frequently expressed HLA-A2 molecules. In this review, the structural and functional distinctiveness of HLA-A2 allelic variants will be discussed.

Abstract
Background The HLA-A*02-B*46 haplotype is one of most frequent haplotypes among Guangdong Han populations. To explore the characteristics of the HLA-A*02-B*46 haplotype in Guangdong Han populations, the genetic polymorphism of HLA-A*02-B*46 haplotype was analysed by PCR-SBT in our study. Findings Among 88 samples with the homozygotes for HLA-A*02-B*46 in the low resolution, 4 different alleles for A*02 (A*0201, A*0203, A*0206, A*0207) and 1 allele for B*46 (B*4601) were identified by PCR-SBT. Among them, the A*0207 allele was the predominant allele. Inversely, among the samples with HLA-A*2-B*46(-), six alleles were detected for A*02 (A*020101, A*0203, A*0205, A*0206 and A*0207), and the A*0201 allele was predominant. On the other hand, the HLA-A*02-B*46 haplotype presented moderate heterozygosis (32.95%). In addition, the linkage with DRB1 was analysed in HLA-A*2-B*46 haplotype, and there existed 10 alleles with DRB1. With the low resolution for DRB1, the other 10 DRB1 alleles all linked with the HLA-A*02-B*46 haplotype except for DRB1*01, DRB1*10, and DRB1*17. Moreover, we found eight alleles of DRB1 in the HLA-A*0207-B*4601 haplotype. Conclusion The polymorphism distribution of the A*02 allele between the HLA-A*02-B*46 and HLA-A*02-B*46(-) haplotypes among the Guangdong Han populations provides useful information for research on unrelated hematopoietic stem cell transplantation (UHSCT), anthropology, and disease association for populations with the HLA-A*02-B*46 haplotype.

Abstract
The origin of the Sinhalese population of Sri Lanka is debated. We subtyped HLA-A*02 in 101 Sinhalese and observed a preponderance of the rare allele HLA-A*0211 which was similar to reported frequencies in northern India. Taken with low-resolution typing for the remaining A, B, C, DR and DQ alleles, these data suggest a North Indian origin for the Sri Lankan Sinhalese.

Abstract
We examined human leucocyte antigen (HLA) gene polymorphisms in the Maonan people from southern China. HLA‐A, ‐B and ‐DRB1 alleles were determined in 108 healthy unrelated Maonan individuals by the polymerase chain reaction‐Luminex method, and haplotype frequencies for HLA‐A, ‐B and ‐DRB1 loci were estimated. The most frequent HLA‐A alleles were A*1101 (35.2%), A*0203 (17.6%), A*0207 (13.4%) and A*2402 (13.4%); HLA‐B alleles were B*1301(19.9%), B*1502 (14.8%), B*4601 (13.4%) and B*4001 (13.4%); HLA‐DRB1 alleles were DRB1*1202 (17.1%), DRB1*1602 (13.0%) and DRB1*1401 (10.7%). The most common haplotypes were A*0207‐B*4601 (10.6%), A*1101‐B*1301 (10.0%), A*1101‐B*4001 (8.4%), B*1502‐DRB1*1202 (12.0%), B*4601‐DRB1*1401 (5.8%), A*1101‐B*1502‐DRB1*1202 (7.1%) and A*0207‐B*4601‐DRB1*1401 (5.3%), profiles that are also found in populations from the southern region of East Asia. Phylogenetic and principal component analyses revealed that the Maonan people belong to the southeastern Asian group and are most closely related to the Buyi people.

Abstract
Recent advances suggest a significant role for the HLA-C locus as a target of alloreactions after bone marrow transplantation. The biological importance of products of the HLA-C locus, both as transplant antigens and as ligands for natural killer (NK) cells, is well established. A total of 10 different serologically defined HLA-Cw antigen specificities (Cw1-Cw10) are encoded by the C locus; however, there are now 151 different alleles that can be identified by molecular methods. Serological definition of Cw alleles therefore includes 20-50% blanks, which cannot be detected by the available antisera. We used the molecular method of polymerase chain reaction (PCR)-based sequence-specific amplification and probe hybridization to define Cw alleles in 91 individuals from the Maratha community, and compared the data with data for 92 serologically typed Maratha individuals from India. We identified Cw*12, Cw*14, Cw*15, Cw*16 and Cw*18, along with the serologically identified Cw*01, Cw*02, Cw*03, Cw*04, Cw*06 and Cw*07 alleles. The HLA-Cw blank allele frequency in the Maratha was reduced from 0.5706 to 0.00. Furthermore, by using a molecular technique, it was possible to identify novel allele subtypes, such as Cw*0104, Cw*0203 and Cw*0707, and a high frequency of Cw* 1801 in the Maratha community compared with other Indian and world populations. Our results will have clinical implications in related and unrelated HLA-matched bone marrow transplantation in India.

Abstract
Human leukocyte antigen (HLA) system is the most polymorphic region known in the human genome. In the present study, we analyzed for the first time the HLA-A gene polymorphisms defined by the high-resolution typing methods-sequence-based typing (SBT) in 161 Northern Chinese Han people. A total of 74 different HLA-A gene types and 36 alleles were detected. The most frequent alleles were A*110101 (GF=0.2360), A*24020101 (GF=0.1646), and A*020101 (GF=0.1553); followed by A*3303 (GF=0.1180), A*3001 (GF=0.0590), and A*310102 (GF=0.0404). The frequencies of following alleles, A*0203, A*0205, A*0206, A*0207, A*030101, A*2423, A*2601, A*3201, and A*3301, are all higher than 0.0093. The homozygous alleles include A*020101, A*110101, A*24020101 and A*310102. Heterozygosity (H), polymorphism information content (PIC), discrimination power (DP) and probability of paternity exclusion (PPE) of HLA-A in the samples were calculated and their values were 0.8705, 0.8491, 0.6014, and 0.9475, respectively. These results by SBT analysis of HLA-A polymorphism in Northern Chinese Han population, especially the allele subtypes character, will be of great interest for clinical transplantation, disease-associated study and forensic identification. Implementation of high-resolution typing methods allows a significantly wider spectrum of HLA variation including rare alleles. This spectrum will further be extensively utilized in many fields.

Abstract
BACKGROUND AND AIMS The immunogenetic basis of autoimmune diseases has become more and more evident. We have analyzed the human leukocyte antigen (HLA) associations with type-1 autoimmune hepatitis (AIH) among patients from western India. METHODS In 20 patients and 120 healthy controls, polymerase chain reaction amplified with sequence specific primers and hybridized with oligoprobes was carried out to elucidate the HLA A, B, C and DRB1 allele associations. RESULTS The study revealed that A*0222 (20% vs 1.66%; P = 0.0001), A*3201 (15% vs 0.83%; P = 0.0004), A*680102 (30% vs 6.66%; P = 0.001), B*35 (40% vs 11.66%; P = 0.001), B*5501 (10% vs 0.83%; P = 0.008), Cw*0102 (15% vs 1.66%; P = 0.002) and Cw*070101 (50% vs 11.66%; P = 2.5E-05) were significantly increased among the A, B and C alleles of AIH patients. Among the HLA DRB1 alleles, DRB1*0301 (20% vs 6.19%; P = 0.03), DRB1*1301 (15% vs 2.65%; P = 0.01), DRB1*14 (30% vs 11.5%; P = 0.02) and DRB1*1501 (40% vs 22.12%; P = 0.08) were increased in AIH patients when compared with the controls. CONCLUSIONS The present study indicates that the HLA susceptibility to type 1 AIH in the different populations studied is complex.
