RCV001946895 | SCV002245541 | pathogenic | Aicardi-Goutieres syndrome 2 | 2023-11-07 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Gln111*) in the RNASEH2B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RNASEH2B are known to be pathogenic (PMID: 17846997). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RNASEH2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 1456507). For these reasons, this variant has been classified as Pathogenic. |

RCV003235636 | SCV003934020 | pathogenic | Aicardi Goutieres syndrome | 2023-05-22 | criteria provided, single submitter | clinical testing | Variant summary: RNASEH2B c.331C>T (p.Gln111X) 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 was absent in 249388 control chromosomes (gnomAD). To our knowledge, no occurrence of c.331C>T in individuals affected with Aicardi Goutieres Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. One ClinVar submitter has assessed the variant since 2014: the variant was classified as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
