Variant summary
Our verdict is Pathogenic. Variant got 15 ACMG points: 16P and 1B. PVS1PP5_Very_StrongBS2_Supporting
The ENST00000323929.8(MRE11):c.1096C>T(p.Arg366Ter) variant causes a stop gained, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000056 in 1,607,808 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. R366R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 07, 2023 | The p.R366* pathogenic mutation (also known as c.1096C>T), located in coding exon 9 of the MRE11A gene, results from a C to T substitution at nucleotide position 1096. This changes the amino acid from an arginine to a stop codon within coding exon 9. This mutation has been identified in a cohort of high-risk breast/ovarian cancer patients (Castéra L et al. Eur. J. Hum. Genet., 2014 Nov;22:1305-13). In addition to the published data, 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. - |
Ataxia-telangiectasia-like disorder Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Apr 20, 2021 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has been observed in individual(s) with a personal and/or family history of breast and/or ovarian cancer (PMID: 24549055). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Arg366*) 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). - |
