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]

The Arg585Leu variant in CBL has not been previously reported in individuals wi th clinical features of Noonan syndrome or in large population studies. Computat ional analyses (biochemical amino acid properties, conservation, AlignGVGD, Poly Phen2, and SIFT) do not provide strong support for or against an impact to the p rotein. In summary, additional information is needed to fully assess the clinica l significance of the Arg585Leu variant. -

This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 585 of the CBL protein (p.Arg585Leu). This variant is present in population databases (rs727504640, gnomAD 0.002%). This missense change has been observed in individual(s) with clinical features of hypertrophic cardiomyopathy (PMID: 25731833). ClinVar contains an entry for this variant (Variation ID: 179116). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CBL protein function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
