HLA complex group 4 pseudogene 5

HLA complex group 4 pseudogene 5 (ENSG00000227766) is located within the HLA genomic region on chromosome 6, a highly polymorphic segment involved in immune regulation and antigen presentation[2][5][4]. However, as a pseudogene, it does not encode a protein or functional RNA and lacks a known biological role. Pseudogenes in the HLA region are remnants of gene duplication events and generally do not participate in antigen processing, immune response, or disease mechanisms[1][3]. This pseudogene is catalogued for genomic annotation, evolutionary studies, and sometimes for genomic haplotyping, but not as a functional or druggable target[1][3].
