Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV004788218 SCV005398693 uncertain significance Autosomal dominant optic atrophy classic form 2020-10-19 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.3, this variant is classified as 3C-VUS. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with ?Mitochondrial DNA depletion syndrome 14 (encephalocardiomyopathic type) (MIM#6168963), {Glaucoma, normal tension, susceptibility to}, (MIM#6066573), Behr syndrome (MIM#210000), optic atrophy 1 (MIM#165500), optic atrophy plus syndrome (MIM#125250). (I) 0108 - This gene is associated with both recessive and dominant disease. Truncating variants and mutations in the C-terminal domain are associated with dominant optic atrophy. Individuals carrying missense variants are clustered within the GTPase domain, generally develop optic atrophy plus syndrome. Lastly, biallelic variants have been associated with early onset Behr syndrome (PMID: 31500643, 28494813, 25012220, 30165240). (I) 0112 - The condition associated with this gene has incomplete penetrance (PMID: 17306754). (I) 0200 - Variant is predicted to result in a missense amino acid change from valine to isoleucine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (SB) 0600 - Variant is located in the annotated dynamin central domain (PMID: 31500643). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (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) 1208 - Inheritance information for this variant is not currently available in this individual. (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign
