Genes affected
PRKAG2 (HGNC:9386): (protein kinase AMP-activated non-catalytic subunit gamma 2) AMP-activated protein kinase (AMPK) is a heterotrimeric protein composed of a catalytic alpha subunit, a noncatalytic beta subunit, and a noncatalytic regulatory gamma subunit. Various forms of each of these subunits exist, encoded by different genes. AMPK is an important energy-sensing enzyme that monitors cellular energy status and functions by inactivating key enzymes involved in regulating de novo biosynthesis of fatty acid and cholesterol. This gene is a member of the AMPK gamma subunit family. Mutations in this gene have been associated with Wolff-Parkinson-White syndrome, familial hypertrophic cardiomyopathy, and glycogen storage disease of the heart. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jan 2015]

not specified Uncertain:1Benign:1
Likely benign, criteria provided, single submitterclinical testingGeneDxMar 29, 2016This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJan 19, 2012Variant classified as Uncertain Significance - Favor Benign. The 685-7C>A varian t (PRKAG2) has not been reported in the literature, but has been detected in 1 i ndividual with HCM tested by our laboratory (this individual's daughter), who ca rried a second pathogenic variant in the TNNI3 gene. The 685-7C>A variant did no t segregate with disease in 1 affected relative, who carried the pathogenic TNNI 3 variant. The 685-7C>A variant is located in the 3' splice region but computati onal analyses do not predict altered splicing, though the accuracy of these tool s is unknown. Although this variant is likely to be benign when seen in isolatio n, we cannot rule out a modifying role. Additional information is needed to full y assess its clinical significance. -
