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]

ACMG classification

Our verdict: Pathogenic. The variant received 14 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.010467779 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
• PS3: PS3 evidence extracted from ClinVar submissions: SCV000185548: RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data).; SCV000682012: Cells derived from these individuals did not show kinase activity (PMID: 23566627, 28126470).; SCV000293075: Cell lines from two of these individuals demonstrated radiosensitivity and absence of ATM protein expression and kinase activity (Mitui 2005, Driessen 2013).; SCV000546808: Studies have shown that disruption of this splice site results in skipping of exon 12, but is expected to preserve the integrity of the reading-frame (internal data).
