An estimated 36% – 54% of 3-methylcrotonyl-CoA carboxylase (3MCC) deficiency is caused by pathogenic variants identified in MCCC1 (PMID: 16010683, 16835865, 22642865).
MCCC1 is methylcrotonyl-CoA carboxylase 1 and it encodes the alpha subunit of the 3-methylcrotonyl-CoA carboxylase (3MCC) enzyme. Alpha subunits are combined with the smaller beta subunits encoded by the MCCC2 gene. The alpha subunit contains a binding site for biotin which is required for the enzyme’s function. 3-MCCC is found in the mitochondria and it is necessary for the fourth step in the breakdown of leucine. It converts 3-methylcrotonyl-CoA to 3-methylglutaconyl-CoA (PMID: 22642865).
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
