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 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.
