RCV001869868 | SCV002301547 | uncertain significance | not provided | 2024-03-14 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 15 of the LZTR1 protein (p.Ala15Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LZTR1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1343621). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on LZTR1 protein function. 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. |
| Ambry Genetics | RCV002329774 | SCV002636494 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2023-03-06 | criteria provided, single submitter | clinical testing | The p.A15V variant (also known as c.44C>T), located in coding exon 1 of the LZTR1 gene, results from a C to T substitution at nucleotide position 44. The alanine at codon 15 is replaced by valine, an amino acid with similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
