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]

The p.P424H variant (also known as c.1271C>A), located in coding exon 9 of the ATM gene, results from a C to A substitution at nucleotide position 1271. The proline at codon 424 is replaced by histidine, an amino acid with similar properties. This alteration has been reported in individuals with breast cancer, including male breast cancer (Tung N et al. Cancer, 2015 Jan;121:25-33; Penkert J et al. Breast Cancer Res, 2018 Aug;20:87; Rizzolo P et al. Int J Cancer, 2019 Jul;145:390-400). This alteration was also detected in both the germline and the tumor in a female diagnosed with ovarian cancer (Coombs CC et al. Clin. Cancer Res., 2018 Jun). This variant was reported in 1/5560 prostate cancer cases and in 0/3353 controls of European ancestry (Karlsson Q et al. Eur Urol Oncol, 2021 Aug;4:570-579). This amino acid position is highly 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This missense variant replaces proline with histidine at codon 424 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function. To our knowledge, functional studies have not been reported for this variant. This variant has been observed in an individual with female breast cancer (PMID: 30086788), male breast cancer (PMID: 30613976), and prostate cancer (PMID: 33436325). This variant has been identified in 6/279764 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. -

Variant summary: ATM c.1271C>A (p.Pro424His) results in a non-conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 248784 control chromosomes (gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1271C>A has been reported in the literature in individuals affected with Breast Cancer (Penkert_2018, Tung_2015), however without strong evidence of causality. These reports therefore, do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four ClinVar submitters (evaluation after 2014) cite the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
