Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 1P and 1B.

PM2_SupportingBP4

This summary comes from the ClinGen Evidence Repository: The ATM c.331+7G>A variant has a GnomAD (v2.1.1) is a singleton in gnomAD v2.1.1 and therefore considered rare (PM2_Supporting). In silico splicing predictors (SpliceAI, Donor Loss: 0%, Donor Gain: 0%; NNSplice, no change) predict that this alteration will not have a significant impact on splicing (BP4). In summary, this variant meets criteria to be classified as a variant of uncertain significance. 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]
