Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PVS1PM3_Strong

This summary comes from the ClinGen Evidence Repository: The ATM c.8786+1G>A variant occurs within the canonical splice donor site (+/- 1,2) of intron 60. It is predicted to cause skipping of a biologically-relevant-exon, resulting in a premature stop codon and nonsense mediated decay. The highest minor allele frequency in gnomAD v2.1.1 is 0.00003517 (4/113738) in the European (non-Finnish) population (PM2_Supporting, BS1, and BA1 are not met). This variant has been detected in at least 6 individuals with Ataxia-Telangiectasia (PMID:26896183, 10817650, 9463314). 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.

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]

C11orf65 (HGNC:28519): (chromosome 11 open reading frame 65) Predicted to be involved in negative regulation of mitochondrial fission and negative regulation of protein targeting to mitochondrion. Predicted to be located in cytosol and mitochondrial outer membrane. [provided by Alliance of Genome Resources, Apr 2022]
