Nemaline myopathy

Nemaline myopathy (referred to in this entry as NM) is characterized by weakness, hypotonia, and depressed or absent deep tendon reflexes. Muscle weakness is usually most severe in the face, the neck flexors, and the proximal limb muscles. The clinical classification defines six forms of NM, which are classified by onset and severity of motor and respiratory involvement: Severe congenital (neonatal) (16% of all individuals with NM). Amish NM. Intermediate congenital (20%). Typical congenital (46%). Childhood-onset (13%). Adult-onset (late-onset) (4%). Considerable overlap occurs among the forms. There are significant differences in survival between individuals classified as having severe, intermediate, and typical congenital NM. Severe neonatal respiratory disease and the presence of arthrogryposis multiplex congenita are associated with death in the first year of life. Independent ambulation before age 18 months is predictive of survival. Most children with typical congenital NM are eventually able to walk. [from GeneReviews]

Neonatal hemochromatosis

Neonatal hemochromatosis (NH) is characterized by hepatic failure in the newborn period and heavy iron staining in the liver. In addition, there is marked siderosis of extrahepatic tissues, including the heart and pancreas (Driscoll et al., 1988). Whitington (2007) postulated that some cases of neonatal hemochromatosis result from maternal alloimmunity directed at the fetal liver, and therefore do not represent an inherited mendelian disorder. Other causes may result from metabolic disease or perinatal infection. In particular, he commented that the disorder is not related to the family of inherited liver diseases that fall under the classification of hereditary hemochromatosis (see, e.g., 235200). Whitington (2007) proposed the term 'congenital alloimmune hepatitis.' In the past, the disorder has loosely been labeled 'neonatal hepatitis' and 'giant cell hepatitis,' which are pathologic findings in the liver representing a common response to a variety of insults, including cholestatic disorders and infection, among others (Fawaz et al., 1975; Knisely et al., 1987; Kelly et al., 2001). [from OMIM]

Myopathy

Your muscles help you move and help your body work. Different types of muscles have different jobs. There are many problems that can affect muscles. Muscle disorders can cause weakness, pain or even paralysis. . Causes of muscle disorders include. -Injury or overuse, such as sprains or strains, cramps or tendinitis . -A genetic disorder, such as muscular dystrophy. -Some cancers. -Inflammation, such as myositis. -Diseases of nerves that affect muscles. -Infections. -Certain medicines. Sometimes the cause is not known.  [from MedlinePlus]

Nemaline bodies

Nemaline rods are abnormal bodies that can occur in skeletal muscle fibers. The rods can be observed on histological analysis of muscle biopsy tissue or upon electron microscopy, where they appear either as extensions of sarcomeric Z-lines, in random array without obvious attachment to Z-lines (often in areas devoid of sarcomeres) or in large clusters localized at the sarcolemma or intermyofibrillar spaces. [from HPO]
