BTLA gene encodes a member of the immunoglobulin superfamily. The encoded protein contains a single immunoglobulin (Ig) domain and is a receptor that relays inhibitory signals to suppress the immune response. Alternative splicing results in multiple transcript variants. Polymorphisms in BTLA gene have been associated with an increased risk of rheumatoid arthritis. [provided by RefSeq, Aug 2011]
