Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 05, 2023 | The p.L165V variant (also known as c.493C>G), located in coding exon 3 of the CBL gene, results from a C to G substitution at nucleotide position 493. The leucine at codon 165 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
RASopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 09, 2021 | In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a CBL-related disease. This sequence change replaces leucine with valine at codon 165 of the CBL protein (p.Leu165Val). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and valine. - |
