Meaning and Definition
A specific type of human gene that codes for proteins on cell surfaces, crucial for immune system recognition.
Human Leukocyte Antigen gene; a highly polymorphic gene complex within the Major Histocompatibility Complex (MHC) on chromosome 6. These genes encode proteins responsible for presenting antigens to T-cells, governing immune responses and influencing tissue compatibility for transplantation. Specific alleles are strongly associated with susceptibility to autoimmune and infectious diseases.

Usage
Meaning in Context
Business
Not applicable.
Academic
Used extensively in biomedical research papers, genetics textbooks, and immunology lectures. Example: 'The study investigated the correlation between the HLA-DQ2 gene and coeliac disease.'
Everyday
Virtually never used. If mentioned, it would be in contexts like personal medical discussions (e.g., 'The doctor said my HLA genes might explain my autoimmune condition.').
Technical
Core terminology in clinical immunology, transplant medicine, pharmacogenomics, and population genetics. Example: 'Pre-transplant screening requires high-resolution HLA gene sequencing.'

Common Mistakes When Using “hla gene”
- Mispronouncing as /huːlɑː/ or /hə.lɑː/ instead of letter-by-letter /eɪtʃ.ɛl.eɪ/.
- Using 'HLA' as a standalone noun without 'gene' or 'type' in non-technical contexts where it would be unclear.
- Incorrect capitalisation: 'hla gene' should be 'HLA gene'.
FAQ
Frequently Asked Questions
Human Leukocyte Antigen. Leukocytes are white blood cells, and antigens are molecules that can trigger an immune response.
They code for the 'self' markers on cells. If the donor's HLA markers are too different, the recipient's immune system will attack the transplanted organ as foreign tissue.
It is a specific type of DNA test that focuses on a particular set of genes (the HLA complex) rather than the whole genome or ancestry markers.
No, your HLA genes are inherited and fixed for life. They are a key part of your genetic identity.
A specific type of human gene that codes for proteins on cell surfaces, crucial for immune system recognition.
Hla gene is usually technical/scientific in register.
Hla gene: in British English it is pronounced /ˌeɪtʃ.ɛlˈeɪ dʒiːn/, and in American English it is pronounced /ˌeɪtʃ.ɛlˈeɪ dʒin/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of HLA as the cell's **H**olding **L**uggage **A**rea. These genes build the 'display shelves' (proteins) that hold up pieces of invaders (antigens) for the immune system's inspection.
Conceptual Metaphor
A **BIRTHMARK FOR THE IMMUNE SYSTEM** – a unique, inherited identifier that your body uses to distinguish 'self' from 'non-self'.
