Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP6

The NM_005188.4(CBL):c.125_127delACC(p.His42del) variant causes a disruptive inframe deletion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000904 in 1,548,456 control chromosomes in the GnomAD database, with no homozygous occurrence. There is a variant allele frequency bias in the population database for this variant (GnomAdExome4), which may indicate mosaicism or somatic mutations in the reference population data. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. H42H) has been classified as Likely benign.

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]

DA (19/12/24): VSD (0). The CBL c.125_127del, located in exon 1 is predicted to result in the deletion of 3 nt resulting in in-frame deletion of Histidine at codon 42, p.(His42del). The variant allele was found at a frequency of 97/179342 alleles (0.05%) in the gnomAD v2.1.1 database, non-cancer dataset. The SpliceAI algorithm predicts no significant impact on splicing. This variant has not been reported in the literature. The variant was identified in the ClinVar** database (3x benign, 2x likely benign). Based on the available evidence to date, this variant is classified as uncertain significance according ACMG guidelines. -
