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]

Variant summary: CBL c.1423G>A (p.Gly475Ser) results in a non-conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 250944 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.1423G>A in individuals affected with Noonan Syndrome-Like Disorder and no experimental evidence demonstrating its impact on protein function have been reported. The following publications have been ascertained in the context of this evaluation (PMID: 27069254, 25224413, 19387008, 23690417, 21828135, 19901108, 20619386, 25952305, 20951944, 19620960, 22733026, 23010802, 29296819). Two ClinVar submitters have assessed the variant since 2014: one classified the variant as likely benign, and one as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

The p.G475S variant (also known as c.1423G>A), located in coding exon 9 of the CBL gene, results from a G to A substitution at nucleotide position 1423. The glycine at codon 475 is replaced by serine, an amino acid with similar properties. This variant was reported in a subject with features of Noonan syndrome, but was also seen in an unaffected parent (Martinelli S et al. Hum Mutat, 2015 Aug;36:787-96). This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
