Ambry Genetics | RCV002340282 | SCV002639451 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2024-10-08 | criteria provided, single submitter | clinical testing | The p.W162R variant (also known as c.484T>C), located in coding exon 5 of the LZTR1 gene, results from a T to C substitution at nucleotide position 484. The tryptophan at codon 162 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. |

RCV003096494 | SCV003453880 | uncertain significance | not provided | 2022-09-30 | criteria provided, single submitter | clinical testing | 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. 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) performed at Invitae indicates that this missense variant is not expected to disrupt LZTR1 protein function. This variant has not been reported in the literature in individuals affected with LZTR1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 162 of the LZTR1 protein (p.Trp162Arg). |
