The NM_005188.4(CBL):c.122_127dupACCACC (p.His41_His42dup) variant causes a disruptive inframe insertion change. The variant results in an in-frame change. The gene CBL is a tumor suppressor gene (CancerMine: 6 TSG, 61 oncogene, 11 driver citations). The gene CBL is a known oncogene (CancerMine: 6 TSG, 61 oncogene, 11 driver citations). The gene CBL is a cancer driver gene (CancerMine: 6 TSG, 61 oncogene, 11 driver citations). Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant allele was found at a cumulative frequency of 0.000174 (AC=271) in the gnomAD database across 1,556,406 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.000847. Variant has been reported in ClinVar as Benign/Likely Benign (no review stars).

Genes affected

CBL (HGNC:1541): (Cbl proto-oncogene) This gene is a proto-oncogene that encodes a RING finger E3 ubiquitin ligase. The encoded protein is one of the enzymes required for targeting substrates for degradation by the proteasome. This protein mediates the transfer of ubiquitin from ubiquitin conjugating enzymes (E2) to specific substrates. This protein also contains an N-terminal phosphotyrosine binding domain that allows it to interact with numerous tyrosine-phosphorylated substrates and target them for proteasome degradation. As such it functions as a negative regulator of many signal transduction pathways. This gene has been found to be mutated or translocated in many cancers including acute myeloid leukaemia, and expansion of CGG repeats in the 5' UTR has been associated with Jacobsen syndrome. Mutations in this gene are also the cause of Noonan syndrome-like disorder. [provided by RefSeq, Jul 2016]
