HLA typing in retinitis pigmentosa
The British Journal of Ophthalmology
|February 1, 1981
Summary
Human Leukocyte Antigen (HLA) antigen frequencies did not differ significantly between retinitis pigmentosa (RP) patients and controls. This suggests HLA types A, B, and C are not strongly associated with common forms of RP.
Area of Science:
- Immunogenetics
- Ophthalmology
- Medical Genetics
Background:
- Retinitis pigmentosa (RP) is a group of inherited retinal diseases.
- Human Leukocyte Antigen (HLA) genes play a crucial role in immune response.
- Previous studies have explored associations between HLA antigens and various diseases.
Purpose of the Study:
- To investigate the association between HLA antigen frequencies and retinitis pigmentosa (RP).
- To compare HLA antigen profiles in patients with different hereditary types of RP against a healthy control group.
Main Methods:
- Serological typing was used to determine HLA antigen profiles.
- 173 patients diagnosed with various hereditary forms of RP were included.
- HLA antigen frequencies (A, B, C loci) were compared between RP patient subgroups and a control population.
Main Results:
- No statistically significant differences were observed in the frequency of any tested HLA (A, B, C) antigen.
- This lack of difference was consistent when comparing autosomal dominant RP and autosomal recessive RP patients to controls.
Conclusions:
- The study found no significant association between HLA antigens (A, B, C) and the hereditary forms of retinitis pigmentosa examined.
- These findings suggest that HLA serological typing may not be a useful biomarker for predicting or diagnosing common forms of RP.
