Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
What causes Rett syndrome? Rett syndrome is typically caused by changes (mutations) in the MECP2 gene. This gene provides instructions for making a protein (MeCP2) needed for the development of the nervous system and normal brain function. Mutations in the MECP2 gene that cause Rett syndrome can change the MeCP2 protein or result in the production of too little protein, which appears to disrupt the normal function of neurons and other cells in the brain. Several conditions caused by changes in other genes (such as FOXG1 syndrome) have overlapping signs and/or symptoms of Rett syndrome. These conditions were once thought to be variant forms of Rett syndrome, but are now usually considered to be separate disorders.
Is Rett syndrome inherited? Although Rett syndrome is a genetic disorder, less than 1 percent of recorded cases are inherited or passed from one generation to the next. Most cases are sporadic, which means the mutation occurs randomly, and are not inherited. A few families have been described with more than one affected family member. These cases helped researchers determine that Rett syndrome has an X-linked dominant pattern of inheritance. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. The inheritance is dominant if one copy of the altered gene in each cell is sufficient to cause the condition.
Peters plus syndrome is a genetic condition characterized by abnormalities of the front part of the eye called the anterior chamber, short stature, cleft lip with or without cleft palate, and distinctive facial features.  The most common eye abnormality is Peters anomaly which involves the thinning and clouding of the cornea and attachment of the iris to the cornea causing blurred vision. Other eye abnormalities such as glaucoma and cataracts are common. The severity of symptoms may vary from person to person. The only gene that has been associated with Peters plus syndrome is B3GALTL. The syndrome is inherited in an autosomal recessive fashion. Treatment varies based on the severity of the symptoms; however, regular appointments with an ophthalmologist and avoidance of agents that increase the risk of glaucoma (e.g., corticosteroids) is recommended.
What treatment is available for Peters plus syndrome? Treatment varies from person to person and is based on the extent of the disease. Once a person has been diagnosed with Peters plus syndrome, the following evaluations are recommended : Eye examination Growth hormone testing Developmental assessment Heart examination Kidney examination Head examination Thyroid testing Hearing assessment Assessment by a ophthalmologist every three months or as indicated is recommended as well as regular developmental assessments. Agents, like corticosteroids, should be avoided, as they increase the risk of glaucoma.
Chromosome 4q deletion is a chromosome abnormality that affects many different parts of the body. People with this condition are missing genetic material located on the long arm (q) of chromosome 4 in each cell. The severity of the condition and the associated signs and symptoms vary based on the size and location of the deletion and which genes are involved. Common features shared by many people with this deletion include distinctive craniofacial features, skeletal abnormalities, heart defects, intellectual disability, developmental delay, and short stature. Most cases are not inherited, although affected people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.
What are the signs and symptoms of chromosome 4q deletion? The signs and symptoms of chromosome 4q deletion vary significantly depending on the size and location of the deletion and which genes are involved. Common features that may be shared by affected people include: Distinctive craniofacial features such as a depressed nasal bridge, cleft lip/palate, and micrognathia Skeletal abnormalities including hip dysplasia and malformations of the fingers, toes, or limbs (arms/legs) Heart defects and/or arrhythmias Hypotonia (reduced muscle tone) Seizures Short stature Developmental delay Intellectual disability Metabolic disorders Gastrointestinal problems Kidney abnormalities
What causes chromosome 4q deletion? People with chromosome 4q deletion are missing genetic material located on the long arm (q) of chromosome 4 in each cell. Scientists suspect that many of the features seen in people affected by this condition are caused by the deletion and/or disruption of certain genes found on 4q. The severity of the condition and the associated signs and symptoms vary depending on the size and location of the deletion and which genes are involved. For example, deletion of the following genes may contribute to the features seen in some affected people: BMP3 - skeletal abnormalities and short stature SEC31A - distinctive craniofacial features PKD2 - kidney abnormalities GRID2, NEUROG2 - neurological problems such as seizures, hypotonia, and delayed motor development (i.e. sitting up, walking, etc) ANK2, HAND2 - heart defects and/or arrhythmias FGF2 - limb (arms and legs) abnormalities Researchers are working to learn more about the other genes on 4q that may contribute to the features seen in people with a chromosome 4q deletion.
How is chromosome 4q deletion diagnosed? There are several different specialized tests that can be used to diagnose a chromosome 4q deletion. These include: Karyotype - a karyotype is a laboratory test that produces an image of a person's chromosomes. This test can be used to diagnose large deletions. FISH - a laboratory technique that is used to detect and locate a specific DNA sequence on a chromosome. During FISH, a chromosome is exposed to a small DNA sequence called a probe that has a fluorescent molecule attached to it. The probe sequence binds to its corresponding sequence on the chromosome. This test can be used in combination with karyotyping for deletions that are too small to be seen on karyotype, alone. However, FISH is only useful if the person ordering the test suspects there is a deletion of a specific region of 4q. Array CGH - a technology that detects deletions that are too small to be seen on karyotype.
How might chromosome 4q deletion be treated? Because chromosome 4q deletion affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this deletion varies based on the signs and symptoms present in each person. For example, babies with congenital heart defects and certain skeletal abnormalities may require surgery. Children with bone or muscle problems and/or delayed motor milestones (i.e. walking) may be referred for physical or occupational therapy. Certain medications may be prescribed to treat seizures. Special education services are often necessary for children with intellectual disability. Please speak to your healthcare provider if you have any questions about your personal medical management plan.

Primary lateral sclerosis is a type of motor neuron disease, where nerve cells that control voluntary muscle movement breakdown and die. In primary lateral sclerosis only the upper motor neurons in the brain are affected. Symptoms often begin with problems in the legs (e.g., weakness, stiffness, spasticity, and balance problems), but may also start with hand clumsiness and changes in speech. The symptoms worsen gradually over time, however people with this condition have a normal life expectancy. Progression of symptoms varies from person to person, some people retain the ability to walk without assistance, others eventually require assistive devices such as canes or wheelchairs. Diagnosis requires extensive testing to exclude other diseases. Treatment may include baclofen and tizanidine to reduce spasticity, quinine or phenytoin to reduce cramps, as well as physical and speech therapy as required.
What are the signs and symptoms of Primary lateral sclerosis? Primary lateral sclerosis (PLS) causes weakness in the voluntary muscles, such as those used to control the legs, arms and tongue. PLS can happen at any age, but it is more common after age 40. A subtype of PLS, known as juvenile primary lateral sclerosis, begins in early childhood. PLS is often mistaken for another, more common motor neuron disease called amyotrophic lateral sclerosis (ALS). However, primary lateral sclerosis progresses more slowly than ALS, and in most cases is not considered fatal. Signs and symptoms of PLS typically take years to progress. The hallmark of PLS is progressive weakness and spasticity of voluntary muscles. The first symptoms are often tripping or difficulty lifting the legs. Other people may be the first to notice a change in the affected person's gait. Occasionally, speaking (dysarthria) and swallowing (dysphasia) difficulties, or arm weakness are the first symptoms. Speech problems can begin with hoarseness, a reduced rate of speaking, excessive clearing of the throat, or slurred speech when a person is tired. In some cases, speech becomes so slurred that others cannot understand it. Drooling can be a problem as well due to weakened bulbar muscles. Many people report painful muscle spasms and other pain. Other common symptoms may include hyperactive reflexes and Babinkski's sign. Wherever symptoms originate, the legs, arms, hands, and speech and swallowing muscles are eventually affected. As the disease progresses, assistive devices such as canes, walkers or wheelchairs are typically needed.

How is primary lateral sclerosis diagnosed? There is no single test that confirms a diagnosis of primary lateral sclerosis (PLS). Because the disease can mimic signs and symptoms of other neurological diseases such as multiple sclerosis and amyotrophic lateral sclerosis (ALS), several tests are done to rule out other diseases. After taking a careful record of an individual's medical history and performing a complete neurological examination, a doctor may order the following tests: Blood work. Blood tests are done to check for infections or other possible causes of muscle weakness. Magnetic resonance imaging (MRI) of the brain and spine. An MRI or other imaging tests may reveal signs of nerve cell degeneration and look for other causes of symptoms, such as structural abnormalities, spinal cord compression, multiple sclerosis and spinal cord tumors. Motor and sensory nerve conduction studies. These tests use a low amount of electrical current to test how quickly the nerves carry impulses through the body, and can indicate damage to nerve cells. Electromyogram (EMG). During this test, the doctor inserts a needle electrode through the skin into various muscles. The electrical activity of the muscles is evaluated when they contract and when they're at rest. This test can measure the involvement of lower motor neurons, which can help to differentiate between PLS and ALS. Cerebrospinal fluid (CSF) analysis. An analysis of the CSF, which is taken during a lumbar puncture in the lower back, can help to rule out multiple sclerosis and other causes of spasticity. After other diseases are ruled out, a doctor may make a preliminary diagnosis of PLS. Sometimes doctors wait three to four years before being sure of the diagnosis, because early ALS can look just like PLS until additional symptoms surface a few years later.
Hypohidrotic ectodermal dysplasia with hypothyroidism and ciliary dyskinesia is a rare condition characterized by alopecia (hair loss); nail dystrophy (abnormal development of the nails); ophthalmic (eye-related) complications; thyroid dysfunction (primary hypothyroidism); hypohidrosis; ephelides (freckles); enteropathy (disease of the intestine); and respiratory tract infections due to ciliary dyskinesia. These features have lead to the acronym ANOTHER syndrome as an alternative name for the condition. The gene that causes the condition is currently unknown but it is thought to be inherited in an autosomal recessive manner. Treatment is generally symptomatic and supportive.

Sertoli cell-only syndrome (SCO syndrome) is a condition of the testes that causes infertility in males due to having only Sertoli cells (cells that nurture immature sperm) lining the seminiferous tubules (tubes inside the testicles where sperm develop). Men typically learn they are affected between ages 20-40 when being evaluated for infertility and are found to have no sperm production (azoospermia). The diagnosis is made based on testicular biopsy findings. Other signs and symptoms are rare, but are secondary to the underlying condition causing SCO syndrome. Most cases are idiopathic (of unknown cause), but causes may include deletions in the azoospermia factor (AZF) region of the Y chromosome, or Y-chromosome microdeletions (referred to as Y chromosome infertility); Klinefelter syndrome; exposure to chemicals and toxins; history of radiation therapy; and history of severe trauma. There is not currently a known effective treatment for the condition. When no germ cells are visible in any seminiferous tubules it is considered SCO type I; if germ cells are present in a minority of tubules is it considered SCO type II.

MYH7-related scapuloperoneal myopathy is an inherited muscular dystrophy characterized by weakness and wasting of the muscles in the lower legs and the area of the shoulder blades. In some individuals, facial muscles may also be affected. While the progression varies from case to case, it tends to be relatively slow. Some cases of scapuloperoneal myopathy are caused by mutations in the MYH7 gene. Autosomal dominant inheritance is suggested in these cases. Treatment is symptomatic and supportive.
