Disease-associated mutations in L1 CAM interfere with ligand interactions and cell-surface expression

Abstract excerpt

Mutations in the L1CAM gene cause a highly variable neurological disease described as X-linked hydrocephalus, MASA syndrome or spastic paraplegia type I. Over one-third of the mutations identified in affected boys are missense, unique to individual families and distributed primarily across the large extracellular domain of the L1 protein. We have examined the effects of 25 missense mutations on binding to...
