Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM3PVS1PS3_Supporting

This summary comes from the ClinGen Evidence Repository: The ATM c.9139C>T (p.Arg3047Ter) variant has a GnomAD (v2.1.1) allele frequency of 0.001768% which is above the PM2 threshold of 0.001% but below the BS1 threshold of 0.05%. This variant is expected to produce an NMD-escaping transcript that adversely affects the critical FATKIN domain (PVS1). This variant has been observed in a compound heterozygous state (confirmed) in multiple individuals with ataxia-telangiectasia (PMIDs: 10980530, 26628246, 19691550, 22649200, PM3_verystrong). This variant is non-functional in a single ATM-specific protein assay (PMID:19431188, PS3_supporting). In summary, this variant meets criteria to be classified as pathogenic based on the ACMG/AMP criteria applied as specified by the HBOP Variant Curation Expert Panel.

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]
