The NM_001197.5(BIK):c.400G>A (p.Glu134Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The gene BIK is a tumor suppressor gene (CancerMine: 1 TSG, 1 driver citations). The gene BIK is a cancer driver gene (CancerMine: 1 TSG, 1 driver citations). The variant allele was found at a cumulative frequency of 0.0000517 (AC=83) in the gnomAD database across 1,604,712 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000382. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain Significance (★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.E134Q: unknown significance (ClinVar VariationId 4459454) The variant has been observed in cBioPortal in 3 samples across 3 studies and 2 cancer types; somatic enrichment level: SUPPORTING_LOW (Observed in a small number of cBioPortal cases.). This exact variant is curated in the UniProt human variants database as Uncertain Significance, associated with Adenomas and Adenocarcinomas.

Genes affected

BIK (HGNC:1051): (BCL2 interacting killer) The protein encoded by this gene shares a critical BH3 domain with other death-promoting proteins, such as BID, BAK, BAD and BAX, that is required for its pro-apoptotic activity, and for interaction with anti-apoptotic members of the BCL2 family, and viral survival-promoting proteins. Since the activity of this protein is suppressed in the presence of survival-promoting proteins, it is suggested as a likely target for anti-apoptotic proteins. [provided by RefSeq, Sep 2011]
