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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineNov 12, 2014The p.Thr276Ala variant in PRKAG2 has not been previously reported in individual s with cardiomyopathy or in large population studies. Computational prediction t ools and conservation analysis do not provide strong support for or against an i mpact to the protein. In summary, the clinical significance of the p.Thr276Ala v ariant is uncertain. -
