An estimated 35-50% of propionic academia cases are attributed to pathogenic variants in PCCA (PMID: 22593918).
The PCCA gene encodes the ÃŽÂ± subunit of the enzyme PropionylCoA carboxylase (PCC). PCC catalyzes the carboxylation of propionylCoA to methylmalonylCoA during the catabolism of the amino acids valine, isoleucine, threonine and methionine; odd chain fatty acids, cholesterol side chains, and thymine and uracil. PCC is a mitochondrial enzyme consisting of two non-identical subunits: ÃŽÂ± and ÃŽÂ² which are encoded by PCCA and PCCB, respectively. Impairment of either PCC subunit leads to reduced PCC activity and propionic acidemia (PMID: 22033733).
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 in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
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.
