Ambry Genetics | RCV000563274 | SCV000665570 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-08-01 | criteria provided, single submitter | clinical testing | The p.L979F variant (also known as c.2937G>T), located in coding exon 19 of the ATM gene, results from a G to T substitution at nucleotide position 2937. The leucine at codon 979 is replaced by phenylalanine, an amino acid with highly similar properties. This amino acid position is 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. |

RCV000791835 | SCV000931099 | uncertain significance | Ataxia-telangiectasia syndrome | 2023-07-08 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 979 of the ATM protein (p.Leu979Phe). 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 ATM-related conditions. ClinVar contains an entry for this variant (Variation ID: 481272). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The phenylalanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
