Invitae RCV000812760 SCV000953083 uncertain significance Neuroblastoma, susceptibility to, 3 2023-12-11 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 833 of the ALK protein (p.Gly833Glu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ALK-related conditions. ClinVar contains an entry for this variant (Variation ID: 656360). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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.
Ambry Genetics RCV002424912 SCV002741078 uncertain significance Hereditary cancer-predisposing syndrome 2022-02-13 criteria provided, single submitter clinical testing The p.G833E variant (also known as c.2498G>A), located in coding exon 15 of the ALK gene, results from a G to A substitution at nucleotide position 2498. The glycine at codon 833 is replaced by glutamic acid, 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.
