| Invitae | RCV000706213 | SCV000835252 | uncertain significance | Neuroblastoma, susceptibility to, 3 | 2022-12-24 | 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: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 582206). This variant has not been reported in the literature in individuals affected with ALK-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1422 of the ALK protein (p.Pro1422Ala). |
| Ambry Genetics | RCV002332508 | SCV002629941 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-21 | criteria provided, single submitter | clinical testing | The p.P1422A variant (also known as c.4264C>G), located in coding exon 29 of the ALK gene, results from a C to G substitution at nucleotide position 4264. The proline at codon 1422 is replaced by alanine, an amino acid with highly 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. |
