Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004595008 SCV005087019 uncertain significance Mitochondrial complex 1 deficiency, nuclear type 6 2023-07-17 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 complex I deficiency, nuclear type 6 (MIM#618228). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from glutamic acid to glutamine. (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) (1 heterozygote, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0704 - Another missense variant comparable to the one identified in this case has limited previous evidence for pathogenicity. This variant (p.(Glu148Lys)) has been reported once as pathogenic (ClinVar), and observed in a compound heterozygous individual with Leigh syndrome (PMID: 20819849). (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
