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]

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: c.1994+10G>A in MRE11A gene is an intronic change that involves a non-conserved nucleotide. 4/5 programs in Alamut predict that this variant does not affect a normal splicing, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at frequency of 0.00317 (384/121126 chrs tested), predominantly in individuals of African descent (0.03533; 366/ 10360 chrs tested). The observed frequency exceeds the maximum expected allele frequency for a pathogenic variant of 0.0000625, suggesting that it is a common polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals in published reports but is cited as Likely Benign/Benign by reputable databases/clinical laboratory. Taking together, the variant was classified as Benign. -
