Invitae | RCV001215148 | SCV001386876 | uncertain significance | Neurofibromatosis, type 1 | 2020-06-21 | criteria provided, single submitter | clinical testing | This sequence change replaces lysine with glutamic acid at codon 1728 of the NF1 protein (p.Lys1728Glu). The lysine residue is moderately conserved and there is a small physicochemical difference between lysine and glutamic acid. 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 NF1-related conditions. This variant is not present in population databases (ExAC no frequency). |
Ambry Genetics | RCV002339562 | SCV002644150 | uncertain significance | Hereditary cancer-predisposing syndrome; Cardiovascular phenotype | 2022-01-10 | criteria provided, single submitter | clinical testing | The p.K1728E variant (also known as c.5182A>G), located in coding exon 36 of the NF1 gene, results from an A to G substitution at nucleotide position 5182. The lysine at codon 1728 is replaced by glutamic acid, an amino acid with similar properties. This amino acid position is conserved. 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. |
