Invitae RCV000647397 SCV000769193 uncertain significance Neuroblastoma, susceptibility to, 3 2023-04-25 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. 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 tolerated. ClinVar contains an entry for this variant (Variation ID: 538195). 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 valine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 1421 of the ALK protein (p.Val1421Gly).
Ambry Genetics RCV002331217 SCV002630836 uncertain significance Hereditary cancer-predisposing syndrome 2022-09-16 criteria provided, single submitter clinical testing The p.V1421G variant (also known as c.4262T>G), located in coding exon 29 of the ALK gene, results from a T to G substitution at nucleotide position 4262. The valine at codon 1421 is replaced by glycine, 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.
