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]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Sep 25, 2014 | Variant classified as Uncertain Significance - Favor Benign. The Thr377Ala varia nt in CBL has been previously identified by our laboratory in 2 siblings with a RASopathy, both of whom also carried a likely pathogenic variant in CBL on the o ther allele (in trans configuration). In addition, these individuals' affected p arent carried the likely pathogenic variant, while these individuals' reportedly unaffected parent carried the Thr377Ala variant. It was also absent from large population studies. Computational prediction tools and conservation analysis su ggest that this variant may impact the protein, though this information is not p redictive enough to determine pathogenicity. In summary, while the clinical sign ificance of the Thr377Ala variant is uncertain, it is more likely benign since h omozygous or compound heterozygous pathogenic variants in the CBL gene are thoug ht to be incapable with life. However, the current knowledge about this gene and its role in disease is limited and, therefore, at this time it cannot be determ ined if this is a mild variant which plays some role in disease. - |
