Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS2
The NM_005188.4(CBL):c.1676G>T(p.Arg559Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000186 in 1,613,902 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R559Q) has been classified as Likely benign.

not specified Uncertain:1
Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: 3/126670 European chromosomes in GnomAd; not in ClinVar, hgmd or google search; conserved, predicted damaging. Identified in 1 individual with HCM. -
B lymphoblastic leukemia lymphoma with hyperdiploidy Uncertain:1

RASopathy Uncertain:1
This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 559 of the CBL protein (p.Arg559Leu). This variant is present in population databases (no rsID available, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with CBL-related conditions. ClinVar contains an entry for this variant (Variation ID: 503532). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -
