Genes affected

PRKAA1 (HGNC:9376): (protein kinase AMP-activated catalytic subunit alpha 1) The protein encoded by this gene belongs to the ser/thr protein kinase family. It is the catalytic subunit of the 5'-prime-AMP-activated protein kinase (AMPK). AMPK is a cellular energy sensor conserved in all eukaryotic cells. The kinase activity of AMPK is activated by the stimuli that increase the cellular AMP/ATP ratio. AMPK regulates the activities of a number of key metabolic enzymes through phosphorylation. It protects cells from stresses that cause ATP depletion by switching off ATP-consuming biosynthetic pathways. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

The c.1129C>G (p.L377V) alteration is located in exon 8 (coding exon 8) of the PRKAA1 gene. This alteration results from a C to G substitution at nucleotide position 1129, causing the leucine (L) at amino acid position 377 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
