The presentation of Ullrich congenital muscular dystrophy in an affected individual is as follows:

- Muscle weakness

- Difficulty walking

- Contractures (neck)

- Joint looseness

Some symptoms consistent with Becker muscular dystrophy are:

Individuals with this disorder typically experience progressive muscle weakness of the leg and pelvis muscles, which is associated with a loss of muscle mass (wasting). Muscle weakness also occurs in the arms, neck, and other areas, but not as noticeably severe as in the lower half of the body.Calf muscles initially enlarge during the ages of 5-15 (an attempt by the body to compensate for loss of muscle strength), but the enlarged muscle tissue is eventually replaced by fat and connective tissue (pseudohypertrophy) as the legs become less used (with use of wheelchair).

In terms of the signs/symptoms of Fukuyama congenital muscular dystrophy it is characterized by a decrease in skeletal muscle tone as well as an impairment in brain and eye development.Initial symptoms of FCMD present in early infancy as decreased ability to feed. Marked differences in facial appearance occur due to decreased muscle tone. Further characteristics include:

- Seizures

- Delay in developmental

- Cardiac issues

- Swallowing difficulty

- Neurological problems

Fukuyama congenital muscular dystrophy also affects the nervous system and various associated parts. FCMD affects normal development of the brain producing a broadly smooth, bumpy shaped cortex named cobblestone lissencephaly as well as various other malformations, notably micropolygyria. Children also experience delayed myelination in the brain.

Possible complications associated with MD are cardiac arrhythmias.(BMD) Becker muscular dystrophy also demonstrates the following:

- Mental impairment (less common in BMD than it is in DMD.)

- Pulmonary failure

- Pneumonia

Most infants with CMD will display some progressive muscle weakness or muscle wasting (atrophy), although there can be different degrees and symptoms of severeness of progression. The weakness is indicated as "hypotonia", or lack of muscle tone, which can make an infant seem unstable.

Children may be slow with their motor skills; such as rolling over, sitting up or walking, or may not even reach these milestones of life. Some of the more rarer forms of CMD can result in significant learning disabilities.

The main symptom of DMD, a progressive neuromuscular disorder, is muscle weakness associated with muscle wasting with the voluntary muscles being first affected, especially those of the hips, pelvic area, thighs, shoulders, and calves. Muscle weakness also occurs later, in the arms, neck, and other areas. Calves are often enlarged. Symptoms usually appear before age six and may appear in early infancy.

Other physical symptoms are:

According to Lewis P. Rowland, in the anthology "Gene Expression In Muscle," if a boy is affected with DMD, the condition can be observed clinically from the moment he takes his first steps. It becomes harder and harder for the boy to walk; his ability to walk usually completely disintegrates between the time the boy is 9 to 12 years of age. Most men affected with DMD become essentially “paralyzed from the neck down” by the age of 21. Muscle wasting begins in the legs and pelvis, then progresses to the muscles of the shoulders and neck, followed by loss of arm muscles and respiratory muscles. Calf muscle enlargement (pseudohypertrophy) is quite obvious. Cardiomyopathy particularly (dilated cardiomyopathy) is common, but the development of congestive heart failure or arrhythmia (irregular heartbeat) is only occasional.

The symptoms of an individual with Limb-girdle Muscular Dystrophy (LGMD) generally has great difficulty walking, going both up and down stairs and raising from a chair. The inability to bend over or squat down is also present. Because of these difficulties, falling can occur on a regular basis. Lifting certain objects, as well as difficulty extending your arms out or above your head, varies from difficult to impossible depending on the severity. Eventually the ability to walk/run deteriorates.

Further "presentations" an individual with LGMD might have are:

The disease inevitably gets worse over time, although progression is more rapid in some patients than others. Eventually the disease can affect other muscles such as the ones located in the face. The disease commonly leads to dependence on a wheelchair within years of symptom onset, but there is high inter-patient variability, with some patients maintaining mobility.

The muscle weakness is generally symmetric, proximal, and slowly progressive. In most cases, pain is not present with LGMD, and mental function is not affected. LGMD can begin in childhood, adolescence, young adulthood or even later, the age of onset is usually between 10 and 30. Both genders are affected equally, when limb-girdle muscular dystrophy begins in childhood the progression appears to be faster and the disease more disabling. When the disorder begins in adolescence or adulthood the disease is generally not as severe and progresses more slowly.There is no sensory neuropathy or autonomic or visceral dysfunction at presentation.

Presentation of symptoms and signs varies considerably by form (DM1/DM2), severity and even unusual DM2 phenotypes. DM1 symptoms for DM2 include problems with executive function (e.g., organization, concentration, word-finding) and hypersomnia. Conduction abnormalities are more common in DM1 than DM2, but all people are advised to have an annual ECG. Both types are also associated with insulin resistance. Myotonic dystrophy may have a cortical cataract with a blue dot appearance, or a posterior subcapsular cataract.

DM2 is generally milder than DM1, with generally fewer DM2 people requiring assistive devices than DM1 people. In addition, the severe congenital form that affects babies in DM1 has not been found in DM2 and the early onset of symptoms is rarely noted to appear in younger people in the medical literature.

Symptoms may appear at any time from infancy to adulthood. DM causes general weakness, usually beginning in the muscles of the hands, feet, neck, or face. It slowly progresses to involve other muscle groups, including the heart. DM affects a wide variety of other organ systems as well.

Congenital muscular dystrophies are autosomal recessively-inherited muscle diseases. They are a group of heterogeneous disorders characterized by muscle weakness which is present at birth and the different changes on muscle biopsy that ranges from myopathic to overtly dystrophic due to the age at which the biopsy takes place.

Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy. The symptom of muscle weakness usually begins around the age of four in boys and worsens quickly. Typically muscle loss occurs first in the upper legs and pelvis followed by those of the upper arms. This can result in trouble standing up. Most are unable to walk by the age of 12. Affected muscles may look larger due to increased fat content. Scoliosis is also common. Some may have intellectual disability. Females with a single copy of the defective gene may show mild symptoms.

The disorder is X-linked recessive. About two thirds of cases are inherited from a person's parents, while one third of cases are due to a new mutation. It is caused by a mutation in the gene for the protein dystrophin. Dystrophin is important to maintain the muscle fiber's cell membrane. Genetic testing can often make the diagnosis at birth. Those affected also have a high level of creatine kinase in their blood.

No cure for muscular dystrophy is known. Physical therapy, braces, and corrective surgery may help with some symptoms. Assisted ventilation may be required in those with weakness of breathing muscles. Medications used include steroids to slow muscle degeneration, anticonvulsants to control seizures and some muscle activity, and immunosuppressants to delay damage to dying muscle cells.

DMD affects about one in 5,000 males at birth. It is the most common type of muscular dystrophy. The average life expectancy is 26; however, with excellent care, some may live into their 30s or 40s. Gene therapy, as a treatment, is in the early stages of study in humans.

In terms of the signs (and symptoms) of oculopharyngeal muscular dystrophy would be consistent with the following:

Though the aforementioned signs/symptoms are the most common, there have been cases though rare, where the peripheral nervous system has had involvement with significant reduction of myelinated fibers

In homozygous cases, this muscular dystrophy is severe and starts earlier in the affected individuals life.

Multicore myopathy, also referred to as minicore myopathy, is associated with small areas of decreased oxidative activities, resulting in areas that appear in this histology as “cores”. These appear through microscopy very similar to central core, however the cores are typically smaller in multicore myopathy. As with congenital fiber type disproportion, patients have a greater number of type 1 fibers. Overall, approximately half of diagnosed individuals report no progression of muscle weakness, while half report a very slow progression.

Fukuyama congenital muscular dystrophy (FCMD) is a rare, autosomal recessive form of muscular dystrophy (weakness and breakdown of muscular tissue) mainly described in Japan but also identified in Turkish and Ashkenazi Jewish patients, fifteen cases were first described on 1960 by Fukuyama.

FCMD mainly affects the brain, eyes, and muscles, in particular, the disorder affects development of the skeletal muscles leading to weakness and deformed appearances, and brain development is blunted affecting cognitive functioning as well as social skills. In 1995, the disorder was linked to mutations in a gene coding for the protein fukutin (the "FCMD" gene). Fukuyama congenital muscular dystrophy is the second most prevalent form of muscular dystrophy in Japan. One out of every 90 people in Japan is a heterozygous carrier.

Congenital fiber type disproportion affects skeletal muscle, typically causing weakness in the shoulders, upper arms, thighs, and hips. Skeletal muscle is made up of two kinds of fiber, type 1 and type 2. In congenital fiber type disproportion, type 1 fibers are not only smaller but often more abundant than type 2 fibers. This leads to affected individuals being able to maintain an active lifestyle, though they usually have lower levels of stamina.

Severity with this disease varies greatly, but people typically present symptoms by the age of one. Individuals do not usually worsen with time, and cases have even been reported of improvements.

Ullrich congenital muscular dystrophy is a form of congenital muscular dystrophy.It is associated with variants of type VI collagen, it is commonly associated with muscle weakness and respiratory problems, though cardiac issues are not associated with this type of CMD. It is named after Otto Ullrich, who is also known for the Ullrich-Turner syndrome.

There are two main types of myotonic dystrophy. Type 1 (DM1), also known as Steinert disease, has a severe congenital form and a milder childhood-onset form as well as an adult-onset form. This disease is most often in the facial muscles, levator palpebrae superioris, temporalis, sternocleidomastoids, distal muscles of the forearm, hand intrinsic muscles, and ankle dorsiflexors. Type 2 (DM2), also known as proximal myotonic myopathy (PROMM), is rarer and generally manifests with milder signs and symptoms than DM1.

Other forms of myotonic dystrophy not associated with DM1 or DM2 genetic mutations have been described. One case which was proposed as a candidate for the "DM3" label, was later characterized as an unusual form of inclusion body myopathy associated with Paget's disease and frontotemporal dementia.

Symptoms of EDMD begin in teenage years with toe-walking, rigid spine, face weakness, hand weakness and calf hypertrophy. Among other signs/symptoms of Emery–Dreifuss muscular dystrophy are:

- "Muscle weakness" EDMD can affect the shoulders and lower legs

- "Cardiac involvement" can affect an individuals heart rate (bradycardia, palpitations)

- "Contractures" of the muscles occurs slowly, eventually leading to the need for orthopedics (walker, cane)

Limb-girdle muscular dystrophy (LGMD) or Erb's muscular dystrophy is a genetically and clinically heterogeneous group of rare muscular dystrophies. It is characterised by progressive muscle wasting which affects predominantly hip and shoulder muscles. LGMD has an autosomal pattern of inheritance and currently has no known cure.

Because of the extreme variability of the disease, an authoritative and scientifically confirmed set of symptoms does not yet exist. The prevalence is widely placed at 1/20,000, but the exact prevalence is not known. A November 2008 report from Orpha.net, an organization backed by the Institut National de la Santé et de la Recherche Médicale (INSERM), listed a prevalence of 7/100,000, but the May 2014 version of this report places the prevalence at 4/100,000. A 2014 population-based study in the Netherlands reported a significantly higher prevalence of 12 in 100,000.[4]

Symptoms:

- Facial muscle weakness (eyelid drooping, inability to whistle, decreased facial expression, depressed or angry facial expression, difficulty pronouncing the letters M, B, and P)

- Shoulder weakness (difficulty working with the arms raised, sloping shoulder)

- Hearing loss

- Abnormal heart rhythm

- Unequal weakening of the biceps, triceps, deltoids, and lower arm muscles

- Loss of strength in abdominal muscles (causing a protuberant abdomen and lumbar lordosis) and eventual progression to the legs

- Foot drop

Centronuclear myopathies (CNM) are a group of congenital myopathies where cell nuclei are abnormally located in skeletal muscle cells. In CNM the nuclei are located at a position in the center of the cell, instead of their normal location at the periphery.

Symptoms of CNM include severe hypotonia, hypoxia-requiring breathing assistance, and scaphocephaly. Among centronuclear myopathies, the X-linked myotubular myopathy form typically presents at birth, and is thus considered a congenital myopathy. However, some centronuclear myopathies may present later in life.

Muscular dystrophy (MD) is a group of muscle diseases that results in increasing weakening and breakdown of skeletal muscles over time. The disorders differ in which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin. Many people will eventually become unable to walk. Some types are also associated with problems in other organs.

There are nine main categories of muscular dystrophy that contain more than thirty specific types. The most common type is Duchenne muscular dystrophy (DMD) which typically affects males beginning around the age of four. Other types include Becker muscular dystrophy, facioscapulohumeral muscular dystrophy, and myotonic dystrophy. They are due to mutations in genes that are involved in making muscle proteins. This can occur due to either inheriting the defect from one's parents or the mutation occurring during early development. Disorders may be X-linked recessive, autosomal recessive, or autosomal dominant. Diagnosis often involves blood tests and genetic testing.

There is no cure for muscular dystrophy. Physical therapy, braces, and corrective surgery may help with some symptoms. Assisted ventilation may be required in those with weakness of breathing muscles. Medications used include steroids to slow muscle degeneration, anticonvulsants to control seizures and some muscle activity, and immunosuppressants to delay damage to dying muscle cells. Outcomes depend on the specific type of disorder.

Duchenne muscular dystrophy, which represents about half of all cases of muscular dystrophy, affects about one in 5,000 males at birth. Muscular dystrophy was first described in the 1830s by Charles Bell. The word "dystrophy" is from the Greek "dys", meaning "difficult" and "troph" meaning "nourish". Gene therapy, as a treatment, is in the early stages of study in humans.

The onset of this disease can begin even before birth but is more commonly in childhood or later into adult life. The progression is slow, with symptoms of weakness and walking difficulties sometimes not presenting until middle age. Early symptoms include Gower's sign ("climbing" up the thighs with the hands when rising from the floor) and tiptoe-walking caused by the beginning of contractures.

Bethlem myopathy affects about 1 in 200,000 people. Contractures of the fingers are a typical symptom of Bethlem myopathy but not of the related Ullrich's myopathy (which does include contractures of arms and legs, as does Bethlem myopathy). Serum creatine kinase is elevated in Bethlem myopathy, as there is ongoing muscle cell death. Patients with Bethlem myopathy may expect a normal life span and continued mobility into adulthood. There is currently no cure for this disorder, but the contractures of the legs can be alleviated with heel-cord surgery followed by bracing and regular physical therapy. Repeated surgeries to lengthen the heel cords may be needed as the child grows to adulthood.

The types of Emery–Dreifuss muscular dystrophy are distinguished by their pattern of inheritance: X-linked, autosomal dominant, and autosomal recessive.

- Autosomal dominant "Emery–Dreifuss muscular dystrophy" individuals experience heart problems with weakness (and wasting) of skeletal muscles and Achilles tendon contractures.

- X-linked "Emery–Dreifuss muscular dystrophy" is the result of the EMD gene, with cardiac involvement and some mental retardation.

- Autosomal recessive individuals with this type of the disorder demonstrate cardiac issues, such as arrhythmia. Individuals who acquire EDMD via the autosomal recessive route have an incidence of 1 in 300,000.

The diagnosis of oculopharyngeal muscular dystrophy can be done via two methods, a muscle biopsy or a blood draw with genetic testing for GCG trinucleotide expansions in the PABPN1 gene. The genetic blood testing is more common.Additionally, a distinction between OPMD and myasthenia gravis or mitochondrial myopathy must be made, in regards to the differential diagnosis of this condition.

Distal muscular dystrophy (or distal myopathy) is a group of disorders characterized by onset in the hands or feet. Many types involve dysferlin, but it has been suggested that not all cases do.

Types include:

DYSF is also associated with limb-girdle muscular dystrophy type 2B.

Distal muscular dystrophy is a type of muscular dystrophy that affects the muscles of the extremities, the hands, feet, lower arms, or lower legs. The cause of this dystrophy is very hard to determine because it can be a mutation in any of at least eight genes and not all are known yet. These mutations can be inherited from one parent, autosomal dominant, or from both parents, autosomal recessive. Along with being able to inherit the mutated gene, distal muscular dystrophy has slow progress therefore the patient may not know that they have it until they are in their late 40’s or 50’s. There are eight known types of distal muscular dystrophy. They are Welander’s distal myopathy, Finnish (tibial) distal myopathy, Miyoshi distal myopathy, Nonaka distal myopathy, Gowers–Laing distal myopathy, hereditary inclusion-body myositis type 1, distal myopathy with vocal cord and pharyngeal weakness, and ZASP-related myopathy. All of these affect different regions of the extremities and can show up as early as 5 years of age to as late as 50 years old. Doctors are still trying to determine what causes these mutations along with effective treatments.
