Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 1436 of the ATM protein (p.His1436Tyr). This variant is present in population databases (rs544891616, gnomAD 0.02%). This missense change has been observed in individual(s) with gastric cancer, melanoma, and/or prostate cancer (PMID: 32066632, 32325837, 33436325, 34262154). ClinVar contains an entry for this variant (Variation ID: 187606). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt ATM protein function with a negative predictive value of 95%. 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. -

This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 1436 of the ATM protein (p.His1436Tyr). This variant is present in population databases (rs544891616, gnomAD 0.02%). This missense change has been observed in individual(s) with gastric cancer, melanoma, and/or prostate cancer (PMID: 32066632, 32325837, 33436325). ClinVar contains an entry for this variant (Variation ID: 187606). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). 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. -

The p.H1436Y variant (also known as c.4306C>T), located in coding exon 28 of the ATM gene, results from a C to T substitution at nucleotide position 4306. The histidine at codon 1436 is replaced by tyrosine, an amino acid with similar properties. This alteration has been reported in at least one subject in a study of 13087 breast cancer cases and 5488 control individuals in the UK (Decker B et al. J. Med. Genet., 2017 11;54:732-741). This alteration has also been reported in individuals diagnosed with cutaneous melanoma, breast cancer, gastric cancer and prostate cancer (Pastorino L et al. Cancers (Basel), 2020 04;12:; Akcay IM et al. Int J Cancer, 2021 01;148:285-295; Carvalho J et al. J Med Genet, 2021 01;58:1-11; Karlsson Q et al. Eur Urol Oncol, 2021 08;4:570-579; Bruno W et al. ESMO Open, 2022 Aug;7:100525). 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. Based on the available evidence, the clinical significance of this variant remains unclear. -

This missense variant replaces histidine with tyrosine at codon 1436 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 cancer, gastric cancer, prostate cancer, and melanoma (PMID: 28779002, 32066632, 32325837, 33436325, 33471991). In a large international case-control study, this variant was reported in 1/60465 breast cancer cases and 3/53458 controls (OR=0.295, 95%CI 0.031 to 2.833, p-value=0.347; PMID: 33471991). This variant has been identified in 8/250480 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. -
