LMF2 (Lipase Maturation Factor 2): LMF2 is a gene that encodes a protein essential for the maturation and proper functioning of lipases, enzymes critical for lipid metabolism. It is involved in the processing and activation of lipases within the endoplasmic reticulum. Defects in LMF2 may contribute to dyslipidaemia and other metabolic disorders related to lipid metabolism.
