Department of Neurology, Johns Hopkins University, Baltimore.

A term male infant is described with an isolated disorder of peripheral myelination. At necropsy, the great majority of medium-to-large axons were unmyelinated. Electron microscopy showed normal axons and redundant lamination of basement membrane, suggestive of early onion bulb pathology. Immunohistochemistry of peripheral nerve showed deficiency of the myelin proteins P2 and P0, myelin basic protein, and myelin-associated glycoprotein. Arrest of peripheral myelination at the promyelin stage appears to be the origin of myelin deficiency.

D009185	Myelin Proteins	MYELIN-specific proteins that play a structural or regulatory role in the genesis and maintenance of the lamellar MYELIN SHEATH structure.	Myelin Protein,Protein, Myelin,Proteins, Myelin
D009186	Myelin Sheath	The lipid-rich sheath surrounding AXONS in both the CENTRAL NERVOUS SYSTEMS and PERIPHERAL NERVOUS SYSTEM. The myelin sheath is an electrical insulator and allows faster and more energetically efficient conduction of impulses. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system). Deterioration of the sheath in DEMYELINATING DISEASES is a serious clinical problem.	Myelin,Myelin Sheaths,Sheath, Myelin,Sheaths, Myelin
D009413	Nerve Fibers, Myelinated	A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the myelinated nerve fibers are completely encased in a MYELIN SHEATH. They are fibers of relatively large and varied diameters. Their NEURAL CONDUCTION rates are faster than those of the unmyelinated nerve fibers (NERVE FIBERS, UNMYELINATED). Myelinated nerve fibers are present in somatic and autonomic nerves.
