Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PS1_Very_Strong PM5 PP3

The ENST00000526567.5(ATM):​c.331_333delAGTinsCGC​(p.Ser111Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S111I) has been classified as Likely pathogenic. 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.

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PS1: Transcript ENST00000526567.5 (ATM) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-108229324-G-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3349804.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
