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]

Familial cancer of breast

Uncertain:4

Uncertain significance, criteria provided, single submitter	clinical testing	Neuberg Centre For Genomic Medicine, NCGM	-	The missense variant c.4910A>G (p.Asp1637Gly) has been submitted to ClinVar as a Variant of Uncertain Significance (VUS). This variant has been observed in an individual affected with breast and/or ovarian cancer (Singh J et al). This p.Asp1637Gly variant has allele frequency of 0.011% in the gnomAD and novel (not in any individuals) in 1000 genome database. The amino acid Asp at position 1637 is changed to a Gly changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Asp1637Gly in ATM is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance (VUS). -
Uncertain significance, criteria provided, single submitter	clinical testing	KCCC/NGS Laboratory, Kuwait Cancer Control Center	May 30, 2023	a variant of uncertain significance was detected in the ATM gene (Asp1637Gly). This sequence change replaces aspartic acid with glycine at codon 1637 of the ATM protein (p.Asp1637Gly). The aspartic acid residue is weakly conserved and there is a moderate physicochemical difference between aspartic acid and glycine. This variant is present in population databases (rs763457172, ExAC 0.08%). This variant has been observed in an individual affected with breast and/or ovarian cancer in a study of 1000 indian families (PMID: 29470806). ClinVar contains an entry for this variant (Variation ID: 407499) with 4 submissions: 1 benign and 3 variant of uncertain significance. In-silico predictions show benign computational verdict based on 11 benign predictions from BayesDel_addAF, DANN, DEOGEN2, EIGEN, LIST-S2, M-CAP, MVP, MutationAssessor, MutationTaster, PrimateAI and SIFT vs 1 pathogenic prediction from FATHMM-MKL and the position is not strongly conserved. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Therefore, it has been classified as a Variant of Uncertain Significance. Heterozygous pathogenic/likely pathogenic mutations in the ATM gene are associated with susceptibility to breast cancer (OMIM 114480 ). -

Uncertain significance, criteria provided, single submitter	clinical testing	Foundation for Research in Genetics and Endocrinology, FRIGE's Institute of Human Genetics	Feb 06, 2024	A heterozygous splice site proximal missense variation in exon 33 of the ATM gene that results in the amino acid substitution of Glycine for Aspartic Acid at codon 1637 (p.Asp1637Gly) was detected. The observed variation has previously been reported in breast and/or ovarian cancer patients [PMID: 29470806, 30093976]. The p.Asp1637Gly variant has not been reported in the 1000 genomes database and has a minor allele frequency of 0.005% in the gnomAD database. The in-silico predictions of the variant are benign by PolyPhen-2 (Hum_Div), SIFT, LRT and Mutation Taster2 tools. The reference codon is conserved in mammals. In summary, the variant meets our criteria to be classified as a variant of uncertain significance. -
