Description

The p.Q1579* pathogenic mutation (also known as c.4735C>T), located in coding exon 30 of the ATM gene, results from a C to T substitution at nucleotide position 4735. This changes the amino acid from a glutamine to a stop codon within coding exon 30. This mutation has been reported in an individual with ataxia-telangiectasia, who also carried a second ATM mutation (Hoche F et al. Pediatr. Neurol. 2014 Sep;51:297-310). It was also identified in a patient with a personal history of breast cancer and a family history of ovarian cancer (Shirts BH et al. Genet. Med. 2016 Oct;18:974-81). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.

Description

This variant changes 1 nucleotide in exon 31 of the ATM gene, creating a premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. This variant has been reported in an individual affected with breast cancer (PMID: 26845104) and in the compound heterozygous state with a second ATM mutation in an individual affected with ataxia telangiectasia (PMID: 25037873). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of ATM function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic.
