RCV001885670 | SCV002137948 | uncertain significance | not provided | 2021-03-26 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with LZTR1-related conditions. This sequence change replaces glutamic acid with glycine at codon 702 of the LZTR1 protein (p.Glu702Gly). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and glycine. |
| Ambry Genetics | RCV002422944 | SCV002725916 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2022-08-30 | criteria provided, single submitter | clinical testing | The p.E702G variant (also known as c.2105A>G), located in coding exon 18 of the LZTR1 gene, results from an A to G substitution at nucleotide position 2105. The glutamic acid at codon 702 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
