Variant summary

Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1_ModeratePS3PM2PP5_Very_Strong

The NM_000051.4(ATM):c.4437-1G>C variant causes a splice acceptor, intron change. The variant allele was found at a frequency of 0.00000186 in 1,612,920 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV000275817: RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data)." and additional evidence is available in ClinVar. 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 16 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.019081889 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.3, offset of 33, new splice context is: atggatgtgtcattacgtAGctt. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PS3

PS3 evidence extracted from ClinVar submissions: SCV000275817: RNA studies have demonstrated that this alteration results in abnormal splicing in the set of samples tested (Ambry internal data).; SCV000622501: Disruption of this splice site has been observed in individuals with clinical features of ataxia-telangiectasia (PMID: 12815592; internal data). Studies have shown that disruption of this splice site is associated with altered splicing resulting in multiple RNA products (internal data).

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 11-108292618-G-C is Pathogenic according to our data. Variant chr11-108292618-G-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 231843.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
