High mobility group box 1 pseudogene 29 (HMGB1P29)

High mobility group box 1 pseudogene 29 (HMGB1P29) is a *pseudogene*—an inactive genetic element derived from the parental HMGB1 gene[1][3][4]. Pseudogenes do not typically encode functional proteins, but some have been shown to play regulatory roles, such as acting as competing endogenous RNAs (ceRNAs) that bind microRNAs and influence expression of their protein-coding progenitors[1][3]. However, there is no evidence in current literature or major gene/protein databases to support HMGB1P29 as a protein-coding gene, drug target, or disease marker.\n\nOther well-described HMGB1-related pseudogenes such as HMGB1P1 are evolutionarily related copies, but they are neither established as therapeutic targets nor functionally significant in a disease context[4]. The literature establishes the general phenomenon of pseudogene regulation in cancer and other diseases, but does not mention HMGB1P29 specifically among functional pseudogenes tested for biological or clinical roles[1][3]. Thus, HMGB1P29:\n- Is *not* a canonical therapeutic target (receptor, enzyme, transporter, etc.)\n- Has *no* known aliases, functional data, or association with drugs or disease roles\n- Is best classified as a non-coding pseudogene, and its entry here may be due to automated annotation or database propagation rather than functional relevance\n\nSummary of Issues:\n- The gene symbol HMGB1P29 refers to an annotated pseudogene, but there is no evidence or literature support for functional, biological, or therapeutic significance, nor for its use as a biomarker, interacting drug target, or potential therapeutic concern.\n- Thus, **is_incorrect** is marked true: this entity is not a biologically relevant or druggable target.\n\nIf detailed information about HMGB1 (the parental gene) is required, that would be a separate and biologically meaningful entry. For now, HMGB1P29 represents a non-functional genetic element with no characterized target attributes[1][3][4].
