Neurofascin is a protein that in humans is encoded by the NFASC gene. [5] [6] [7]
Neurofascin is an L1 family immunoglobulin cell adhesion molecule (see L1CAM) involved in axon subcellular targeting and synapse formation during neural development. [7] [8]
A homozygous mutation causing loss of Nfasc155 causes severe congenital hypotonia, contractures of fingers and toes and no reaction to touch or pain. [9]
