Stats by Source
Total, split by cell line (COSMIC CL / DepMap / PubMed) vs tissue (COSMIC primary tissue)
Total = all mutations for this gene across every source.
Cell line = COSMIC Cell Lines Project + DepMap + PubMed.
Tissue = COSMIC primary-tissue (patient tumour) samples.
Total can exceed cell line + tissue: COSMIC tissue-derived models sit only in global, and a peptide can be shared across both.

Function
HMGB1P1 · High mobility group box 1 pseudogene 1
This gene may represent an evolving retropseudogene of the high-mobility group box 1 gene, which has multiple pseudogenes. This gene has an intact open reading frame, where the length of encoded protein is conserved, compared to the high-mobility group box 1 protein. However, due to the lack of conclusive evidence for specific transcription at this location, this locus is currently represented as a pseudogene. [provided by RefSeq, Jan 2010]
Isoforms & Proteins
1 transcript · UniProt mapping is sequence-verified (AA-safe)
Each Ensembl transcript (ENST) this gene is mutated on, with its matched UniProt accession.
The mapping is sequence-verified: the UniProt sequence is identical to the transcript translation, so amino-acid positions line up exactly. A * marks an unreviewed (TrEMBL) entry.
Counts are mutations and unique mutant peptides on each transcript.
| Transcript | UniProt | Mutations | Peptides |
|---|---|---|---|
| ENST00000522557 | B2RPK0 | 9 | 9 |
Gene Properties
Recurrent Mutations
All 9 amino-acid changes on canonical ENST00000522557 · needle height = samples · drag the mini-map to zoom
A lollipop / needle plot – the standard way to show recurrent mutations along a protein (as used by cBioPortal and MutationMapper).
X-axis = amino-acid position in the protein.
Needle height & head size = how often that exact amino-acid change was observed (its recurrence). Tall/large heads are mutational hotspots.
The most recurrent changes are labelled; hover any needle for the change, position and counts.
Mutation frequency across cancer types
% of samples with a missense/complex mutation in HMGB1P1 · cell line vs tissue
For each cancer type, the fraction of samples that carry at least one missense/complex mutation anywhere in HMGB1P1 – counted as distinct samples (a sample counts once no matter how many mutations it has).
Split into cell line and tissue; each cell shows mutated / total and the percentage. Cohorts with <20 samples are omitted. Ordered by combined frequency.
| Cancer type | Cell lines | Tissue samples |
|---|---|---|
| Glioblastoma | 2/98 2% | 0/0 0% |
| Head and Neck Carcinoma | 2/85 2% | 0/1574 0% |
| Neuroblastoma | 1/87 1% | 0/1331 0% |
| Non-Small Cell Lung Carcinoma | 1/304 0% | 0/1390 0% |
| Glioma | 1/52 2% | 0/2127 0% |
| Melanoma | 1/210 0% | 0/1899 0% |
| Colorectal Carcinoma | 1/143 1% | 0/3239 0% |
Mutation Distribution
Where HMGB1P1 is mutated · all tissues, split by cell line vs tissue
How many mutations in HMGB1P1 were found in each tissue, across the whole database.
Each bar is a tissue (cell-line and tissue names are merged to the standard tissue), split into cell line and tissue (patient tumour) contributions.
This shows the cancer-context where this gene is recurrently altered.
GTEx Expression
Median TPM across 54 healthy tissues
Median gene expression (TPM) in normal, non-cancer human tissues from the GTEx project.
Useful for judging tumour specificity – a strong neoantigen target ideally comes from a gene with low expression in healthy tissues.
