LPIN2 (Lipin 2): LPIN2 is a protein that plays a crucial role in lipid metabolism and energy production, especially in converting phosphatidic acid to diacylglycerol, a key step in the synthesis of triglycerides and phospholipids. It also helps regulate gene expression related to lipid metabolism and inflammation. Mutations in LPIN2 are linked to Majeed syndrome, which is characterized by chronic recurrent multifocal osteomyelitis, dermatitis, and dyserythropoietic anemia, highlighting its significance in both metabolic and immune functions.
