Myeloma protein
Myeloma protein (M protein, paraprotein, monoclonal protein) is the abnormal monoclonal immunoglobulin secreted by clonal plasma cells in myeloma, MGUS, and related gammopathies, measured by electrophoresis, immunofixation, free light chain assays, and increasingly mass spectrometry.
Myelomalacia
Myelomalacia is softening of the spinal cord after ischemia, compression, or contusion; seen on MRI as T2 hyperintensity, it marks chronic cord injury in degenerative cervical myelopathy and predicts white cord syndrome after decompression.
Myelomeningocele repair
Myelomeningocele repair is the surgical closure of an open spinal birth defect, performed within days of birth or prenatally; prenatal repair reduces shunt-dependent hydrocephalus and improves early motor function.
Myelomeningocele with hydrocephalus
Myelomeningocele with hydrocephalus (ICD-11 LA02.00) is an open spinal neural tube defect combined with ventricular CSF accumulation. Hydrocephalus affects 15–25% of MMC babies; prenatal repair (MOMS trial) roughly halves shunt placement rates versus postnatal repair.
Myelopathy
Myelopathy is spinal cord dysfunction, usually from compression; types are cervical, thoracic, and lumbar, with degenerative cervical myelopathy the most common cause in adults, treated with bracing, therapy, medication, or decompression surgery.
Myeloperoxidase deficiency
Myeloperoxidase deficiency (MPO deficiency) is an autosomal recessive primary immunodeficiency caused by MPO gene mutations on chromosome 17, impairing neutrophil HOCl generation; most carriers of the complete defect stay asymptomatic except for candidal risk with diabetes.
Myeloproliferative neoplasm
Myeloproliferative neoplasms (MPNs) are clonal blood cancers in which the bone marrow overproduces red cells, platelets, or white cells. Types include CML, polycythemia vera, essential thrombocythemia, and primary myelofibrosis, driven by JAK2, CALR, and MPL mutations.
Myeloschisis
Myeloschisis (ORPHA:645398) is a severe open neural tube defect with a flat, exposed neural placode lacking a sac, always with Chiari II malformation; distinct from myelomeningocele, with different fetal surgery outcomes.
Myenteric plexus
Myenteric plexus, also called Auerbach's plexus, is the ganglionated nerve network between the circular and longitudinal muscle layers of the gut that drives peristalsis as part of the enteric nervous system.
