The NM_005591.4(MRE11):c.454C>T (p.His152Tyr) variant causes a missense change involving the alteration of a conserved nucleotide. The gene MRE11 is a known oncogene (CancerMine: 3 oncogene citations). The variant allele was found at a cumulative frequency of 0.0000116 (AC=17) in the gnomAD database across 1,461,522 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000153. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 9.91). Variant has been reported in ClinVar as Uncertain Significance (★★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.H152D: Uncertain_significance (ClinVar VariationId 1799791, 1 star); p.H152L: Uncertain_significance (ClinVar VariationId 1799821, 1 star); p.H152P: Uncertain_significance (ClinVar VariationId 584531, 2 stars)

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]
