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]

Ataxia-telangiectasia syndrome Uncertain:2
Uncertain significance, no assertion criteria provided | clinical testing | Natera, Inc. | Mar 31, 2021 | - - |
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | May 13, 2020 | In summary, this is a novel in-frame deletion with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acid is currently unknown. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an ATM-related disease. This sequence change deletes 3 nucleotides from exon 17 of the ATM mRNA (c.2589_2591delTAG). This leads to the deletion of 1 amino acid residue in the ATM protein (p.Ser864del) but otherwise preserves the integrity of the reading frame. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 24, 2019 | The c.2593_2595delAGT variant (also known as p.S865del) is located in coding exon 16 of the ATM gene. This variant results from an in-frame AGT deletion at nucleotide positions 2593 to 2595. This results in the in-frame deletion of a serine at codon 865. This amino acid position is not well conserved in available vertebrate species. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
