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