RCV001294928 | SCV001483828 | uncertain significance | Neuroblastoma, susceptibility to, 3 | 2024-10-23 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 306 of the ALK protein (p.Gly306Arg). 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: 998990). 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. 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 | RCV004951448 | SCV005589037 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-11-05 | criteria provided, single submitter | clinical testing | The p.G306R variant (also known as c.916G>A), located in coding exon 3 of the ALK gene, results from a G to A substitution at nucleotide position 916. The glycine at codon 306 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. |
