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]

Likely benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Aug 24, 2023	Variant summary: ATM c.103C>A alters a non-conserved nucleotide resulting in a synonymous change. Consensus agreement among computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 9.9e-05 in 282600 control chromosomes (gnomAD), predominantly at a frequency of 0.00088 within the African or African-American subpopulation in the gnomAD database. This frequency is not significantly higher than estimated for a pathogenic variant in ATM causing Breast Cancer (9.9e-05 vs 0.001), allowing no conclusion about variant significance. c.103C>A has been reported in the literature without evidence for causality (e.g. Gumy Pause_2003, Bernstein_2010). These reports do not provide unequivocal conclusions about association of the variant with Breast Cancer. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 20305132, 12673804). Ten ClinVar submitters have assessed the variant since 2014: one classified the variant as benign, and nine as likely benign. Based on the evidence outlined above, the variant was classified as likely benign. -
