Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_000051.4(ATM):c.3601T>A(p.Phe1201Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000868 in 1,613,416 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. F1201S) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:2
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 13, 2022 | The p.F1201I variant (also known as c.3601T>A), located in coding exon 24 of the ATM gene, results from a T to A substitution at nucleotide position 3601. The phenylalanine at codon 1201 is replaced by isoleucine, an amino acid with highly similar properties. This alteration was identified in 1/278 individuals from a cohort of BRCA1/2-negative individuals with early-onset breast cancer via multiplex panel testing of 22 cancer susceptibility genes (Maxwell KN et al. Genet Med, 2015 Aug;17:630-8). This variant was also identified in a cohort of 3,579 African males diagnosed with prostate cancer who underwent multi-gene panel testing of 19 DNA repair and cancer predisposition genes (Matejcic M et al. JCO Precis Oncol, 2020 Jan;4:32-43) and was identified as germline in a cohort of 690 patients with myeloid malignancy (Li ST et al. Leukemia, 2020 Jun;34:1675-1678). 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. - |
Uncertain significance, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Sep 07, 2023 | This missense variant replaces phenylalanine with isoleucine at codon 1201 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in individuals affected with breast and prostate cancer in the literature (PMID: 25503501, 32832836). This variant has been identified in 7/282334 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
