Genes affected
MCCC1 (HGNC:6936): (methylcrotonyl-CoA carboxylase subunit 1) This gene encodes the large subunit of 3-methylcrotonyl-CoA carboxylase. This enzyme functions as a heterodimer and catalyzes the carboxylation of 3-methylcrotonyl-CoA to form 3-methylglutaconyl-CoA. Mutations in this gene are associated with 3-Methylcrotonylglycinuria, an autosomal recessive disorder of leucine catabolism. [provided by RefSeq, Jul 2008]

not specified Benign:2
Likely benign, no assertion criteria providedclinical testingGene Friend Way, National Innovation CenterJul 28, 2023minor Allele frequency of this variant is 0.013 in Vietnamese population (sample size 5000) which is relatively high for a pathogenic/likely pathogenic mutation. This variant is also synonymous therefore, we classified this as likely benign -
Likely benign, criteria provided, single submitterclinical testingGeneDxApr 08, 2016This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
