| Invitae | RCV000536579 | SCV000648650 | uncertain significance | Neuroblastoma, susceptibility to, 3 | 2022-11-08 | 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. 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 C45"). ClinVar contains an entry for this variant (Variation ID: 470786). This variant has not been reported in the literature in individuals affected with ALK-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces isoleucine, which is neutral and non-polar, with asparagine, which is neutral and polar, at codon 762 of the ALK protein (p.Ile762Asn). |
| Ambry Genetics | RCV002448744 | SCV002734726 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-03-16 | criteria provided, single submitter | clinical testing | The p.I762N variant (also known as c.2285T>A), located in coding exon 13 of the ALK gene, results from a T to A substitution at nucleotide position 2285. The isoleucine at codon 762 is replaced by asparagine, an amino acid with dissimilar 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. |
