PPA2 (Inorganic Pyrophosphatase 2): PPA2 encodes an enzyme called inorganic pyrophosphatase, which catalyzes the hydrolysis of pyrophosphate (PPi) to inorganic phosphate (Pi). This enzymatic activity is important for cellular energy metabolism and nucleotide biosynthesis. Dysfunctions in PPA2 may impact energy production and nucleotide metabolism....
