Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PVS1 PM3_Strong

This summary comes from the ClinGen Evidence Repository: The c.3078-1G>A variant in ATM occurs within the canonical splice donor/acceptor site (+/- 1,2) of intron 20. It is predicted to cause skipping of a biologically-relevant-exon, resulting in a frameshift leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism. The highest population minor allele frequency in gnomAD v2.1.1 is (0. 0.0018%) (2/113536 alleles) in the European (non-Finnish) population. (PM2_Supporting, BS1, and BA1 are not met). This variant has been detected in at least 1 individual with Ataxia-Telangiectasia (PMID:10234507). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant hereditary breast cancer and autosomal recessive Ataxia-Telangiectasia based on the ACMG/AMP criteria applied, as specified by the HBOP VCEP (PVS1, PM3_Strong).

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]
