Butyrophilin subfamily 2 member A3, pseudogene (BTN2A3P)

BTN2A3P (Butyrophilin subfamily 2 member A3, pseudogene) is a non-protein-coding member of the butyrophilin gene family, localized to chromosome 6 within the human major histocompatibility complex (MHC). Unlike its functional paralogs, BTN2A3P is a pseudogene, so it does not encode a full-length functional protein[2][5]. The butyrophilin gene family is involved with immune modulation and regulation of T cell activity, but BTN2A3P’s precise biological relevance remains undetermined. Some associations link its expression to immune-related tissues and suggest possible involvement in immune response regulation, yet there is no experimental confirmation of a functional protein product or validated disease role. BTN2A3P is not considered a receptor, enzyme, or actionable drug target, and it has no established applications as a biomarker for patient selection or efficacy monitoring[3][5]. Summary: BTN2A3P is a pseudogene—commonly misinterpreted as a protein-coding immune receptor—without evidence for direct biological activity, drug interactions, or therapeutic relevance[2][3][5].
