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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGenetic Services Laboratory, University of ChicagoJun 12, 2020DNA sequence analysis of the CBL gene demonstrated a sequence change in intron 3, c.591-8C>T. This change does not appear to have been previously described in patients with CBL-related disorders and has been described in the gnomAD database in one individual which corresponds to a population frequency of 0.00040% (dbSNP rs749291716). This sequence change is not clearly predicted to have a deleterious effect on splicing based on in silico splice prediction programs. It is possible that this sequence change represents a benign sequence change in the CBL gene that has not been identified to date. The functional significance of this sequence change is not known at present and its contribution to this patient's disease phenotype cannot definitively be determined. -
