The variant received -1 classification points (ACGS-UK Somatic Oncogenicity v2025). B3_Supporting

The NM_001379180.1(ESRRB):c.460+4C>T variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The gene ESRRB is a tumor suppressor gene (CancerMine: 2 TSG, 2 driver citations). The gene ESRRB is a cancer driver gene (CancerMine: 2 TSG, 2 driver citations). The variant allele was found at a cumulative frequency of 0.0000219 (AC=32) in the gnomAD database across 1,460,138 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000341. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★). The variant has been observed in cBioPortal in 1 sample across 1 study and 1 cancer type; somatic enrichment level: NONE (Observed in at most one deduplicated cBioPortal case.).

Genes affected

ESRRB (HGNC:3473): (estrogen related receptor beta) This gene encodes a protein with similarity to the estrogen receptor. Its function is unknown; however, a similar protein in mouse plays an essential role in placental development. [provided by RefSeq, Jul 2008]
