Genes affected

MRE11 (HGNC:7230): (MRE11 homolog, double strand break repair nuclease) This gene encodes a nuclear protein involved in homologous recombination, telomere length maintenance, and DNA double-strand break repair. By itself, the protein has 3' to 5' exonuclease activity and endonuclease activity. The protein forms a complex with the RAD50 homolog; this complex is required for nonhomologous joining of DNA ends and possesses increased single-stranded DNA endonuclease and 3' to 5' exonuclease activities. In conjunction with a DNA ligase, this protein promotes the joining of noncomplementary ends in vitro using short homologies near the ends of the DNA fragments. This gene has a pseudogene on chromosome 3. Alternative splicing of this gene results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Variant summary: MRE11 c.1516G>T (p.Glu506X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 3.2e-05 in 250580 control chromosomes. c.1516G>T has been reported in the literature in individuals affected with Ataxia Telangiectasia-Like Disorder (Raslan_2021) . To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 33426167). ClinVar contains an entry for this variant (Variation ID: 140941). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Glu506*) in the MRE11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MRE11 are known to be pathogenic (PMID: 23080121, 23912341). This variant is present in population databases (rs587781384, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with breast or ovarian cancer, fallopian tube cancer, and lung cancer (PMID: 24763289, 26786923, 26845104, 28125075). ClinVar contains an entry for this variant (Variation ID: 140941). For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.E506* pathogenic mutation (also known as c.1516G>T), located in coding exon 13 of the MRE11A gene, results from a G to T substitution at nucleotide position 1516. This changes the amino acid from a glutamic acid to a stop codon within coding exon 13. 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. -
