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]

The ATM p.Leu2910= variant was not identified in the literature nor was it identified in the GeneInsight-COGR, Cosmic, MutDB, LOVD 3.0, or in ATM-LOVD databases. The variant was identified in dbSNP (ID: rs551041839) as "With Likely benign allele", ClinVar (classified as benign by Invitae, GeneDx; as likely benign by Ambry Genetics, Color Genomics, Integrated Genetics/Laboratory Corporation of America), and Clinvitae databases. The variant was identified in control databases in 153 of 246230 chromosomes (1 homozygous) at a frequency of 0.001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include South Asian in 151 of 30782 chromosomes (freq: 0.004905), and Ashkenazi Jewish in 2 of 9848 chromosomes (freq: 0.0002) while the variant was not observed in the African, Other, Latino, European, East Asian, or Finnish populations. The p.Leu2910= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
