Stats by Source
Global, split by cell line (COSMIC CL / DepMap / PubMed) vs tissue (COSMIC primary tissue)
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
FAM208A · Protein TASOR
Core component of the HUSH complex, a multiprotein complex that specifically mediates epigenetic repression of mobile genetic elements, such as retroviruses and transposable elements (PubMed:26022416, PubMed:28581500, PubMed:29211708, PubMed:32976585, PubMed:33009411, PubMed:37433650). The HUSH complex represses LINE-1 (L1) retrotransposons that are still capable of transposition (PubMed:29211708, PubMed:32976585). Silencing events often occur within introns of transcriptionally active genes, and lead to the down-regulation of host gene expression (PubMed:29211708). The HUSH complex also represses exogenous retroviruses and synthetic transgenes (PubMed:26022416). The HUSH complex also represses expression of latent herpes simplex virus (PubMed:39589886). Mediates silencing of unintegrated retroviral DNA following recruitment by ZNF638: some part of the retroviral DNA formed immediately after infection remains unintegrated in the host genome and is transcriptionally repressed (PubMed:30487602). The HUSH complex is recruited to genomic loci rich in H3K9me3 and is required to maintain transcriptional silencing by promoting recruitment of SETDB1, a histone methyltransferase that mediates further deposition of H3K9me3, as well as MORC2, a chromatin remodeler that compacts chromatin (PubMed:26022416, PubMed:28581500). Within the HUSH complex, TASOR acts as the central scaffold which recruits MPHOSPH8 and PPHLN1 to mobile genetic elements and mediates association with SETDB1 and MORC2 (PubMed:32976585, PubMed:33009411, PubMed:39589886). The ability to silence mobile genetic elements plays a crucial role in early embryonic development: it is required to maintain epiblast cell fitness and cell division (By similarity)
Isoforms & Proteins
4 transcripts · 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.

Gene Properties
Recurrent Mutations
Top recurrent amino-acid changes along the protein · needle height = number of 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 Distribution
Where FAM208A is mutated · all tissues, split by cell line vs tissue
How many mutations in FAM208A 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.
