Congenital hereditary muscular dystrophy

An inherited congenital myopathic condition characterized by weakness and hypotonia in infancy and delayed motor development. Muscle biopsy reveals a condensation of myofibrils and myofibrillar material in the central portion of each muscle fiber.
A group of inherited congenital myopathic conditions characterized clinically by weakness, hypotonia, and prominent hypoplasia of proximal muscles including the face. Muscle biopsy reveals large numbers of rod-shaped structures beneath the muscle fiber plasma membrane. This disorder is genetically heterogeneous and may occasionally present in adults.

ICD-9-CM Diagnosis 359.1

Hereditary progressive muscular dystrophy

A heterogeneous group of genetic disorders characterized by progressive MUSCULAR ATROPHY and MUSCLE WEAKNESS beginning in the hands, the legs, or the feet. Most are adult-onset autosomal dominant forms. Others are autosomal recessive.
An X-linked recessive muscle disease caused by an inability to synthesize DYSTROPHIN, which is involved with maintaining the integrity of the sarcolemma. Muscle fibers undergo a process that features degeneration and regeneration. Clinical manifestations include proximal weakness in the first few years of life, pseudohypertrophy, cardiomyopathy (see MYOCARDIAL DISEASES), and an increased incidence of impaired mentation. Becker muscular dystrophy is a closely related condition featuring a later onset of disease (usually adolescence) and a slowly progressive course.
A heterogeneous group of inherited MYOPATHIES, characterized by wasting and weakness of the SKELETAL MUSCLE. They are categorized by the sites of MUSCLE WEAKNESS; AGE OF ONSET; and INHERITANCE PATTERNS.
Pelvic muscle weakness and atrophy associated with pseudohypertrophy of the calves. Two basic types are recognized: Duchenne muscular dystrophy (Type I) Synonym: childhood pseudohypertrophic muscular dystrophy with the onset of symptoms between the ages of 3 and 5 years, the patients becoming bedridden by age of 12 and death by age 20 to 25 years. Becker muscular dystrophy (Type II) Synonyms: adult pseudohypertrophic muscular dystrophy mild or benign X-linked recessive muscular dystrophy with onset of symptoms between the ages of 20 and 30 years and relatively normal life expectancy in most cases. Atrophic changes begin in the muscles of the pectoral girdle and trunk and extend to the extremities. As their size increases, the muscles become firm and resilient, but their strength diminishes and, eventually, atrophy ensues. Inability to rise to an upright position without turning to the side, waddling gait, and progressive weakness are the characteristic features. Pseudohypertrophy of the calf muscles is due to fibrous tissue and fat infiltration. Involvement of the heart consists of usually terminal cardiomyopathy. Fasciculation and atrophy of the tongue with dysphagia, dysarthria, and thickened nasal speech are usually associated. Usually mild and static mental retardation occurs in about 30% DMD patients most children having normal, even superior intelligence.
A heterogenous group of inherited muscular dystrophy that can be autosomal dominant or autosomal recessive. There are many forms (called LGMDs) involving genes encoding muscle membrane proteins such as the sarcoglycan (SARCOGLYCANS) complex that interacts with DYSTROPHIN. The disease is characterized by progressing wasting and weakness of the proximal muscles of arms and legs around the HIPS and SHOULDERS (the pelvic and shoulder girdles).
A progressive disorder involving pelvic and scapular girdle muscles marked by weakness of proximal muscles of hip and shoulder areas with variable psychiatric disorders and occasional mild mental retardation. Type IA (LGMD1A) Synonym: proximal limb-girdle muscular dystrophy type 1A A slowly progressive form of muscular dystrophy affecting the proximal limb muscles but sparing the face. (159000) Type IB (LGMD1B) Synonym: proximal limb-girdle muscular dystrophy type 1B A slowly progressive form of muscular dystrophy differing from LGMD1A by the nasal quality of speech. (OMIM 159001) Type 2 (LGMD2, LGMD2A) Synonyms: Leyden-Mobius syndrome distal muscular dystrophy pelvofemoral muscular dystrophy pelvofemoral syndrome tibial muscular dystrophy Muscular dystrophy involving first the pelvic or, less commonly, shoulder girdle with occasional pseudohypertrophy of the calves with onset usually in childhood but sometimes in later stages of life. Muscle wasting tends to be asymmetric when the upper limbs are first involved. Progression of disease varies with inability to walk usually taking place at about 20 to 30 years of onset. Facial weakness and contractures may occur later. (OMIM 253600) Type 3 (LGMD3, LGMD2B) A slowly progressive form of muscular dystrophy involving the pelvic girdle with onset in the late teens.
An autosomal dominant degenerative muscle disease characterized by slowly progressive weakness of the muscles of the face, upper-arm, and shoulder girdle. The onset of symptoms usually occurs in the first or second decade of life. Affected individuals usually present with impairment of upper extremity elevation. This tends to be followed by facial weakness, primarily involving the orbicularis oris and orbicularis oculi muscles. (Neuromuscul Disord 1997;7
An autosomal dominant hereditary disease that presents in late in life and is characterized by DYSPHAGIA and progressive ptosis of the eyelids. Mutations in the gene for POLY(A)-BINDING PROTEIN II have been associated with oculopharyngeal muscular dystrophy.

Myotonic disorders

An autosomal dominant neuromuscular disorder which usually presents in early adulthood, characterized by progressive muscular atrophy (most frequently involving the hands, forearms, and face), myotonia, frontal baldness, lenticular opacities, and testicular atrophy. Cardiac conduction abnormalities, diaphragmatic weakness, and mild mental retardation may also occur. Congenital myotonic dystrophy is a severe form of this disorder, characterized by neonatal MUSCLE HYPOTONIA, feeding difficulties, respiratory muscle weakness, and an increased incidence of MENTAL RETARDATION.
A dominantly inherited muscle disease that begins in early childhood and is characterized by severe myotonia (delayed relaxation of a muscle) after forceful voluntary contractions. Muscular hypertrophy is common and myotonia may impair ambulation and other movements. Myotonia typically becomes less severe with repetitive voluntary contractions of the affected muscles. Generalized myotonia (of Becker) is an autosomal recessive variant of myotonia congenita that may feature more severe myotonia and muscle wasting.
Diseases characterized by MYOTONIA, which may be inherited or acquired. Myotonia may be restricted to certain muscles (e.g., intrinsic hand muscles) or occur as a generalized condition. These disorders may be associated with abnormal muscle SODIUM CHANNEL and CHLORIDE CHANNELS. MYOTONIC DYSTROPHY and MYOTONIA CONGENITA represent two relatively common forms of this disorder. Proximal myotonic myopathy often presents with myotonia and muscle pain in early adulthood and later in life thigh muscle weakness and cataracts develop.

ICD-9-CM Diagnosis 359.3

Familial periodic paralysis

A heterogenous group of inherited disorders characterized by recurring attacks of rapidly progressive flaccid paralysis or myotonia. These conditions have in common a mutation of the gene encoding the alpha subunit of the sodium channel in skeletal muscle. They are frequently associated with fluctuations in serum potassium levels. Periodic paralysis may also occur as a non-familial process secondary to THYROTOXICOSIS and other conditions.
An autosomal dominant familial disorder characterized by recurrent episodes of skeletal muscle weakness associated with falls in serum potassium levels. The condition usually presents in the first or second decade of life with attacks of trunk and leg paresis during sleep or shortly after awakening. Symptoms may persist for hours to days and generally are precipitated by exercise or a meal high in carbohydrates.
