Pathogenic variants in the G6PD gene are the only known cause of glucose-6-phosphate dehydrogenase deficiency (PMID: 8861278).
The G6PD gene encodes the glucose-6-phosphate dehydrogenase enzyme which catalyses the first reaction in the pentose phosphate pathway, providing reducing power to all cells in the form of NADPH which enables cells to counterbalance oxidative stress. Since red blood cells do not contain mitochondria, they depend on pentose phosphate pathway for NADPH production, and thereby, defend against oxidative damage (PMID: 24146346)
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.
