Genes affected
SUGCT (HGNC:16001): (succinyl-CoA:glutarate-CoA transferase) This gene encodes a protein that is similar to members of the CaiB/baiF CoA-transferase protein family. Mutations in this gene are associated with glutaric aciduria type III. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010]

Glutaryl-CoA oxidase deficiency Pathogenic:2Uncertain:1
Likely pathogenic, criteria provided, single submitterclinical testingNeuberg Centre For Genomic Medicine, NCGM-The stop-gained variant c.301C>T p.Arg101Ter in the SUGCT gene has been reported in an individual in homozygous state affected with Glutaric Aciduria, Type 3 Niska-Blakie et al., 2020; Sherman et al., 2008. The variant has 0.02% allele frequency in gnomAD Exomes and is novel not in any individuals in 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain significance/ Pathogenic. However, study on multiple affected individuals and functional studies on the pathogenicity of the variant is unavailable. This variant is predicted to cause loss of normal protein function through protein truncation. Loss of function variants has been previously reported to be disease causing. For these reasons, this variant has been classified as Likely Pathogenic. -
