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]

Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsSep 05, 2019This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Uncertain significance, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The ATM c.4110-4T>C variant was not identified in the literature nor was it identified in the LOVD 3.0, database. The variant was identified in dbSNP (ID: rs777186156) as "With Uncertain significance allele", and in ClinVar (classified as likely benign by Invitae; as uncertain significance by Ambry Genetics). The variant was identified in control databases in 2 of 246126 chromosomes at a frequency of 0.000008 (Genome Aggregation Database Feb 27, 2017). The variant was observed in European population in 2 of 111608 chromosomes (freq: 0.00002), while the variant was not observed in the African, Other, Latino, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. The c.4110-4T>C variant is located in the 3' splice region but does not affect the invariant -1 and -2 positions. However, positions -3 and -5 to -12 are part of the splicing consensus sequence and variants involving these positions sometimes affect splicing. However, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
