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]

This variant is denoted ATM c.8269-18_8269-15delTTTA or IVS56-18_IVS56-15delTTTA and consists of a deletion of four nucleotides at the -18 to -15 position in intron 56 of the ATM gene. The normal sequence with the bases that are deleted in braces is ggta[ttta]atct. Multiple in silico models predict this variant to impact the nearby natural acceptor site, and to possibly cause abnormal gene splicing. However, in the absence of RNA or functional studies, the actual effect of this variant is unknown. ATM c.8269-18_8269-15delTTTA was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. This variant has not, to our knowledge, been published in the literature as pathogenic or benign. The nucleotides that are deleted are not conserved across species. Based on the currently available information, we consider ATM c.8269-18_8269-15delTTTA to be a variant of uncertain significance. -
