ELFN2 (Extracellular Leucine-Rich Repeat and Fibronectin Type III Domain Containing 2): ELFN2 is a gene that encodes a protein with leucine-rich repeat and fibronectin type III domains. These domains suggest its involvement in cell adhesion, signaling, and interactions with the extracellular matrix. ELFN2's functions in neural development and synaptic plasticity are of particular interest, as it may play a role in modulating neuronal connections in the brain....
