Invitae | RCV000810935 | SCV000951176 | uncertain significance | Neuroblastoma, susceptibility to, 3 | 2022-12-26 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 654877). This variant has not been reported in the literature in individuals affected with ALK-related conditions. This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 27 of the ALK protein (p.Gln27Glu). |
Ambry Genetics | RCV002422785 | SCV002681700 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-02-16 | criteria provided, single submitter | clinical testing | The p.Q27E variant (also known as c.79C>G), located in coding exon 1 of the ALK gene, results from a C to G substitution at nucleotide position 79. The glutamine at codon 27 is replaced by glutamic acid, 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. |
