RCV003514642 | SCV004320929 | pathogenic | Progressive sclerosing poliodystrophy | 2023-09-15 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Glu1084Glyfs*21) in the POLG gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POLG are known to be pathogenic (PMID: 18546365). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with POLG-related conditions. For these reasons, this variant has been classified as Pathogenic. |

RCV004786941 | SCV005398567 | pathogenic | Mitochondrial disease | 2020-07-02 | criteria provided, single submitter | clinical testing | Based on the classification scheme VCGS_Germline_v1.3.3, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with POLG-related mitochondrial disorder. (I) 0108 - This gene is associated with both recessive and dominant disease (OMIM). (I) 0112 - The condition associated with this gene has incomplete penetrance (OMIM). (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction) (exon 20 of 23). (SP) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (v2 and v3). (SP) 0701 - Other NMD predicted variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar). (SP) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign |
