Invitae | RCV000800153 | SCV000939853 | uncertain significance | Neuroblastoma, susceptibility to, 3 | 2024-01-25 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 1215 of the ALK protein (p.Pro1215Gln). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 645965). 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 | RCV001020786 | SCV001182312 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-11-15 | criteria provided, single submitter | clinical testing | The p.P1215Q variant (also known as c.3644C>A), located in coding exon 23 of the ALK gene, results from a C to A substitution at nucleotide position 3644. The proline at codon 1215 is replaced by glutamine, an amino acid with similar properties. This amino acid position is not well conserved in available vertebrate species. 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. |
