Associated disorders

The PRKAG2 gene is associated with autosomal dominant glycogen storage related Wolff-Parkinson-White syndrome (MedGen UID: 12162) with or without hypertrophic cardiomyopathy (HCM) (MedGen UID: 331466).

Pathogenic PRKAG2 variants are a rare cause of HCM.

The PRKAG2 gene encodes the gamma2 subunit of AMP-activated protein kinase, which is involved in maintaining cellular enery homeostasis. Specifically in cardiomyocytes, AMP-activated protein kinases perform a variety of functions to maintain an adequate energy supply for normal cardiac function.

Assay and technical information

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.
