Clinical Info

Birdshot chorioretinopathy (BSCR) is a rare form of autoimmune uveitis that can lead to severe visual impairment. 
Greater than 95% of patients diagnosed with BSCR carry the human leukocyte antigen (HLA)A*29 allele of the major 
histocompatibility complex (MHC). The MHC family of genes code for a highly variable set of cell surface glycoproteins 
(HLAs) that play a critical role in presenting antigens to T cell receptors to elicit an immune response.
