Invitae RCV000812799 SCV000953124 pathogenic Ataxia-telangiectasia-like disorder 2018-10-11 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 7 of the MRE11 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is present in population databases (rs759130031, ExAC 0.02%). This variant has been observed in in individuals affected with Nijmegen breakage syndrome-like severe microcephaly or ovarian cancer (PMID: 29348823, 21227757). ClinVar contains an entry for this variant (Variation ID: 230014). Experimental studies have shown that this splice site change leads to skipping of exon 7, which is predicted to result in an absent protein product (PMID: 21227757). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in MRE11 are known to be pathogenic (PMID: 23080121, 23912341). For these reasons, this variant has been classified as Pathogenic.
