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 submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 21, 2013Variant classified as Uncertain Significance - Favor Benign. The Pro782Leu varia nt in CBL has been identified by our laboratory in this patient's son, however i t has not been seen in the literature. This variant has been identified in 0.7% (30/4398) of African American chromosomes from a large population study by the N HLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/; dbSNP rs222907 3). Computational analyses (biochemical amino acid properties, conservation, Ali gnGVGD, PolyPhen2, and SIFT) suggest that the Pro782Leu variant may impact the p rotein, though this information is not predictive enough to determine pathogenic ity. In summary, additional information is needed to fully assess the clinical s ignificance of the Pro782Leu variant. -
Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJul 27, 2020Variant summary: CBL c.2345C>T (p.Pro782Leu) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00078 in 251460 control chromosomes, predominantly at a frequency of 0.0082 within the African or African-American subpopulation in the gnomAD database, including 1 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 3280 fold of the estimated maximal expected allele frequency for a pathogenic variant in CBL causing Noonan Syndrome And Related Conditions phenotype (2.5e-06), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. c.2345C>T has been reported in the literature in at least one individual affected with Noonan Syndrome (Justino_2015). This report does not provide unequivocal conclusions about association of the variant with Noonan Syndrome And Related Conditions. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -

CBL-related disorder Benign:1Other:1
Benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 12, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
