Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PVS1PS3PP5_Very_Strong

The NM_000051.4(ATM):c.103C>T(p.Arg35*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000868 in 1,613,460 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000826949: Experimental studies have shown that this premature translational stop signal affects ATM function (PMID:8968760, 12637545, 15101044, 17699107)." and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. R35R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay. The gene ATM is included in the ClinGen Criteria Specification Registry.

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]

ACMG classification

Specifications for ATM are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Pathogenic. The variant received 20 ACMG points.

PVS1

Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000826949: Experimental studies have shown that this premature translational stop signal affects ATM function (PMID: 8968760, 12637545, 15101044, 17699107).; SCV000185123: Functional studies show that this mutation leads to the elimination of ATM protein synthesis (Gilad S et al. Hum. Mol. Genet. 1996 Dec;5:2033-7) as well as increased radiosensitivity (Gutiérrez-Enríquez S et al. Genes Chromosomes Cancer. 2004 Jun;40:109-19).; SCV000293091: Published functional studies demonstrate a damaging effect: loss of ATM protein and reduced cell survival when exposed to radiation compared to wild-type (Fernet 2003);; SCV005038979: Experimental studies have shown that this premature translational stop signal affects ATM function (PMID: 8968760, 12637545, 15101044, 17699107).; SCV005900536: Functional studies indicate heterozygotes with this variant may have reduced (approximately half) ATM protein expression (PMID: 34723800, 8968760).

PP5

Variant 11-108227806-C-T is Pathogenic according to our data. Variant chr11-108227806-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 3025.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
