Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM3 PVS1 PM5_Supporting

This summary comes from the ClinGen Evidence Repository: The c.1564_1565del (p.Glu522Ilefs*43) variant in ATM is a frameshift variant predicted to cause a premature stop codon in a biologically-relevant-exon leading to nonsense mediated decay in a gene in which loss-of-function is an established disease mechanism. This alteration results in a termination codon upstream of the most C-terminus pathogenic alteration (ATM p.Arg3047*), as classified by the HBOP VCEP, and is expected to be more deleterious. This variant has been detected in numerous unrelated individuals with Ataxia-Telangiectasia (PMIDs: 26896183, 10330348, 9792409, 12497634, 15880721, 31407689, 30549301, 30772474, 9887333, 28126470, 23566627, 22213089, 21792198, 17985259, 8755918, 16266405, 21965147, 10817650, 8789452, 9463314, 19535770). The highest population minor allele frequency in gnomAD v4.1.0 0.00007373 in the European (non-Finnish) population (PM2_Supporting, BS1, and BA1 are not met). In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant ATM-related cancer predisposition and autosomal recessive ataxia-telangiectasia based on the ACMG/AMP criteria applied, as specified by the HBOP VCEP.

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]
