Victorian Clinical Genetics Services, Murdoch Childrens Research Institute RCV002470395 SCV002767785 uncertain significance L-2-hydroxyglutaric aciduria 2020-10-19 criteria provided, single submitter clinical testing Based on the classification scheme VCGS_Germline_v1.3.3, this variant is classified as VUS-3C. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with L-2-hydroxyglutaric aciduria (MIM#236792). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from serine to asparagine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v3) <0.01 for a recessive condition (2 heterozygotes, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v3) (3 heterozygotes, 0 homozygotes). (I) 0504 - Same amino acid change has been observed in placental mammals. (SB) 0600 - Variant is located in the annotated FAD dependent oxidoreductase domain (PDB). (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. An alternative change (p.Ser344Arg) has been reported as a VUS (ClinVar). (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
