Overview
• Why does HLA matter in transplantation?
• HLA• Where is it found?• What does it do?• Tissue typing? • What does the nomenclature mean and how do we
classify ‘matching’ and ‘mismatching’?• Polymorphism
• Some examples

What is HLA? What is it for?
• Human Leukocyte Antigen
• Discovered: in mice (1937), humans (1954)
• Function: to present peptides to T cells, thus allowing elimination of foreign particles and recognition of self (so in transplants this has to be modulated)

MHC Sequencing Consortium, 1999
• One of the most gene-dense regions of the genome
• 224 genes identified within the 3.6 Mb
• 40% of the genes have functions within the immune response
• HLA is the most polymorphic region in the human genome

HLA Nomenclature
• Gene names HLA-A or HLA-DRB1
• Antigen names A2 or DR1
• Allele names A*020101 or DRB1*01010101

Low level of resolution A*02
Medium level (string) A*0201/0205/0209/0240
High level A*020101
Level of resolution
Antigen matched
Allele matched
Type is ONE OF these four: Antigen matched BUT do not know if allele matched
![Page 31: HLA: matching and donor selection Dr Bronwen Shaw Consultant in haematopoietic cell transplantation Royal Marsden Hospital Anthony Nolan Trust.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649c7c5503460f949301ad/html5/thumbnails/31.jpg)
• Using medium level resolution typing it is possible to exclude some
but not all alleles from a group, hence the National Marrow Donor
Program (NMDP) codes.
B*1501 or B*1502 = B*15AB
B*1501/1502/1505/1515/1521/1545/1556/1570 = B*15FGR
• This is important for donor selection i.e. you may be able to tell if a donor is
definitely MISMATCHED but not matched

Linkage Disequilibrium/ Haplotypes
• LD: Alleles occur together with a greater frequency than would be expected by chance
– B/C strong, DR/DQ strong, A less strong, DP weak
– e.g. B*0801 - 99% will be Cw*0701– But B*1801 either Cw*0501, *0701
– e.g DRB1*1501 - will be DQB1*0602– But DRB1*0401 either Cw*0301, *0302
• Haplotype: A group of genes inherited together– e.g. A*0101,B*0801,Cw*0701,DRB1*0301,DQB1*0201
![Page 35: HLA: matching and donor selection Dr Bronwen Shaw Consultant in haematopoietic cell transplantation Royal Marsden Hospital Anthony Nolan Trust.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649c7c5503460f949301ad/html5/thumbnails/35.jpg)

Example 1: VUD search
• Patient:– A*0101, B*0801, DRB1*0301
• Finding a donor:– Common haplotype - therefore likely– Usually in strong LD - therefore ‘predictable’– Even at low resolution (A1, B8, DR3) good
chance of being matched
![Page 37: HLA: matching and donor selection Dr Bronwen Shaw Consultant in haematopoietic cell transplantation Royal Marsden Hospital Anthony Nolan Trust.](https://reader036.fdocuments.us/reader036/viewer/2022062409/56649c7c5503460f949301ad/html5/thumbnails/37.jpg)
Example 1: Data entry• Patient:
– A*0101, B*0801, DRB1*0301
• Donor:– A1, B8, DRB1 03: Antigenic match for A, B,
DRB1 • No data can be entered for C, DQB1, DPB1• No data can be entered for allele level matching
– A*0101, B*0801, DRB1*0301: Allelic and antigenic match for A, B, DRB1
• No data can be entered for C, DQB1, DPB1

Example 2: VUD search
• Patient:– A*0201, B*1801, DRB1*0401
• Finding a donor:– Less strong LD - therefore ‘ NOT predictable’
i.e. equal chance of C being *0701, *0501, *1203; DQB1 50/50 chance of *0301, *0302
– At low resolution (A2, B18, DRB4) unable to predict this will match
