How the counts split by source
Stats by Source

Global = all mutations for this gene across every source.

Cell line = COSMIC Cell Lines Project + DepMap + PubMed.

Tissue = COSMIC primary-tissue (patient tumour) samples.

Global can exceed cell line + tissue: COSMIC tissue-derived models sit only in global, and a peptide can be shared across both.

Function

FAM92A · CBY1-interacting BAR domain-containing protein 1

Plays a critical role in regulating mitochondrial ultrastructure and function by maintaining the integrity of mitochondrial morphology, particularly the organization of cristae (PubMed:30404948). Preferentially binds to negatively charged phospholipids like cardiolipin and phosphatidylinositol 4,5-bisphosphate enhancing its interaction with mitochondrial membranes (PubMed:30404948). Induces membrane curvature and tubulation, which are critical for maintaining mitochondrial ultrastructure and the organization of cristae (PubMed:30404948). Plays a crucial role in ciliogenesis (PubMed:27528616, PubMed:30395363). May play a role in limb development through its role in ciliogenesis (PubMed:30395363). Plays a key role in the correct positioning of the annulus, a septin-based ring structure in the sperm flagellum, serving both as a physical barrier and a membrane diffusion barrier that separates the midpiece (MP) from the principal piece (PP) (By similarity). This positioning is essential for proper sperm motility and function (By similarity). Interacts with CBY3 to form a complex which localizes to the curved membrane region of the flagellar pocket (By similarity). By doing so, may provide stability and rigidity to the periannular membrane to prevent membrane deformation (By similarity). This function is crucial for halting annulus migration at the proximal end of the fibrous sheath-containing PP (By similarity)

About the isoform mapping
Isoforms & Proteins

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.

Gene Properties

Recurrent Mutations

Top recurrent amino-acid changes along the protein · needle height = number of mutations

What this lollipop shows
Recurrent Mutations

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 counts by tissue
Mutation Distribution

How many mutations in FAM92A 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.

About the expression data
GTEx Expression

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.
