Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004788512 SCV005398150 uncertain significance Mitochondrial disease 2024-10-09 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with mitochondrial disease (MONDO#0044970), POLG-related. (I) 0108 - This gene is associated with both recessive and dominant disease. Variants are usually inherited in a recessive manner, however progressive external ophthalmoplegia can also be dominant when heterozygous variants are located in the highly conserved active site of motif B of the polymerase domain (PMID: 30451971). (I) 0112 - Autosomal dominant progressive external ophthalmoplegia associated with this gene has incomplete penetrance (OMIM). (I) 0200 - Variant is predicted to result in a missense amino acid change from serine to proline. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (5 heterozygotes, 0 homozygotes). (I) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0710 - Another missense variant comparable to the one identified in this case has inconclusive previous evidence for pathogenicity. p.(Ser462Leu) has been reported as a variant of uncertain significance (ClinVar) and has been observed in a control individual in the literature (PMID: 27987238). (I) 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) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) by trio analysis. (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
