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]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

DNA sequence analysis of the CBL gene demonstrated a sequence change, c.2363G>A, in exon 15 that results in an amino acid change, p.Arg788Gln. This sequence change has been described in the gnomAD database with a frequency of 0.08% in the African American/African subpopulation (dbSNP rs150811339). The p.Arg788Gln change affects a moderately conserved amino acid residue located in a domain of the CBL protein that is not known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Arg788Gln substitution. This sequence change does not appear to have been previously described in patients with CBL-related disorders. Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Arg788Gln change remains unknown at this time. -

Collection Method: clinical testing

Variant summary: CBL c.2363G>A (p.Arg788Gln) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.00011 in 251456 control chromosomes. The observed variant frequency is approximately 44.54 fold of the estimated maximal expected allele frequency for a pathogenic variant in CBL causing Noonan Syndrome And Related Conditions phenotype (2.5e-06). To our knowledge, no occurrence of c.2363G>A in individuals affected with Noonan Syndrome And Related Conditions and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 180823). Based on the evidence outlined above, the variant was classified as likely benign. -
