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]

Likely pathogenic, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Oct 22, 2018	The MRE11A c.1714C>T (p.Arg572Ter) variant is a stop-gained variant predicted to cause a premature truncation of the protein. The p.Arg572Ter variant has been reported in at least two studies in which it is found in a compound heterozygous state in two pairs of siblings from two families with ataxia-telangiectasia-like disorder (Pitts et al. 2001; Delia et al. 2004; Federighi et al. 2017). Control data are unavailable for this variant, which is reported at a frequency of 0.00013 in the European (non-Finnish) population of the Exome Aggregation Consortium. The p.Arg572Ter variant protein could not be detected in proband cells due to destabilisation of the variant by nonsense-mediated mRNA decay. In addition, functional assays in patient lymphoblastoid cell lines demonstrated that the p.Arg572Ter variant protein resulted in a defective MRN complex and exhibited enhanced radio sensitivity in colony survival assays (Pitts et al. 2001; Delia et al. 2004). Based on the evidence, the p.Arg572Ter variant is classified as likely pathogenic for ataxia-telangiectasia-like disorder. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Dec 11, 2023	Variant summary: MRE11A c.1714C>T (p.Arg572X) 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 6e-05 in 251278 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in MRE11A causing Ataxia Telangiectasia-Like Disorder (6e-05 vs 0.0013), allowing no conclusion about variant significance. c.1714C>T has been reported in the literature in individuals affected with Ataxia Telangiectasia-like Disorder (Delia_2004, Pitts_2001), along with individuals affected with pancreatic cancer (Hu_2018) and breast cancer (Lolas Hamameh_2017). These data indicate that the variant is likely to be associated with disease. In addition, functional studies utilizing samples from compound heterozygote patients found the nonsense change to cause NMD leading to lack of MRE11A protein expression and causing an increased radiosensitivity (Delia_2004). The following publications have been ascertained in the context of this evaluation (PMID: 28152038, 29922827, 28486781, 15269180, 11371508, 10612394). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 29, 2023	This sequence change creates a premature translational stop signal (p.Arg572*) 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 also known as p.R571X. This premature translational stop signal has been observed in individual(s) with ataxia-telangiectasia-like disorder (PMID: 11371508, 15269180). This variant is present in population databases (rs137852761, gnomAD 0.01%). ClinVar contains an entry for this variant (Variation ID: 8784). For these reasons, this variant has been classified as Pathogenic. -

The p.R572* pathogenic mutation (also known as c.1714C>T), located in coding exon 14 of the MRE11A gene, results from a C to T substitution at nucleotide position 1714. This changes the amino acid from an arginine to a stop codon within coding exon 14. This mutation was reported in two siblings with ataxia telangiectasia-like disorder (ATLD) and was found to result in nonsense-mediated decay (Pitts SA et al. Hum. Mol. Genet. 2001 May;10:1155-62). In addition, two Italian siblings with ATLD were found to be compound heterozygous for this mutation, and their clinical course is well documented (Delia D et al. Hum. Mol. Genet. 2004 Sep;13:2155-63; Palmeri S et al. Cerebellum. 2013 Aug;12:596-9). Of note, this alteration is also designated as R571X in published literature. 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. -
