Schwartz Jampel syndrome type 1 (SJS1) is a genetic disorder that affects bone and muscle development. Signs and symptoms may include muscle weakness and stiffness, abnormal bone development, joint contractures,  short stature, small, fixed facial features, and eye abnormalities (some of which may impair vision). SJS1 can be divided into two subtypes differentiated by severity and age of onset. Type 1A, considered classic SJS, is the most commonly recognized type. Individuals with type 1A typically develop more mild symptoms later in childhood, while individuals with type 1B have symptoms that are more severe and are apparent immediately after birth. SJS1 is caused by mutations in the HSPG2 gene which makes a protein called perlecan. SJS1 is thought to be inherited in an autosomal recessive manner; however, some cases reported in the medical literature suggest an autosomal dominant inheritance pattern. Treatment for both type 1A and 1B aims to normalize muscle activity through various methods including massage and stretching, medications such as Botulinum toxin, and surgery.  There is a more severe, distinct condition called Stuve-Wiedemann syndrome which is caused by mutations in the LIFR gene. At one time cases of Stuve-Wiedemann syndrome were referred to as Neonatal Schwartz Jampel syndrome type 2. Click on the link above to learn more about this syndrome.
What causes Schwartz Jampel syndrome type 1? Schwartz Jampel syndrome type 1 (SJS1) is caused by mutations in the HSPG2 gene. The HSPG2 gene codes for the protein perlecan, which is found in muscle and cartilage. Although the role of the perlecan protein is not fully understood, it is thought to play an essential role in many biological activities such as cell signaling and cellular structure. In SJS1, it is suspected that a disturbance in perlecan function leads to a deficiency of acetylcholinesterase, an enzyme involved in breaking down acetylcholine, a neurotransmitter that sends messages between nerves, leading to muscle contraction. If acetylcholine is not broken down, it may lead to an prolonged muscle contraction or stiffening of the muscles (myotonia).
How is Schwartz Jampel syndrome type 1 inherited? The majority of cases of Schwartz Jampel syndrome type 1 (SJS1) are inherited in an autosomal recessive pattern. This means that to have the disorder, a person must have a mutation in both copies of the responsible gene in each cell. Individuals with SJS1 inherit one mutated copy of the gene from each parent, who is referred to as a carrier. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). Rarely, cases of SJS1 with autosomal dominant inheritance have been reported. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition.
How is Schwartz Jampel syndrome type 1 diagnosed? The diagnosis of Schwartz Jampel syndrome type 1 (SJS1) is suspected based on clinical findings including characteristic facial features, skeletal features, and muscle stiffness (myotonia). Studies that may be useful in diagnosing  SJS1 include: blood tests (which may show elevated serum creatine kinase or adolase); imaging studies; muscle biopsy; and electromyography (EMG)/nerve conduction studies. Genetic testing of the HSPG2 gene may additionally be helpful to confirm the diagnosis.
How might Schwartz Jampel syndrome type 1 be treated? Treatment of Schwartz Jampel syndrome type 1 (SJS1) aims to reduce stiffness and cramping of muscles. This might include nonpharmacologic modalities such as massage, warming of muscles, and gradual strengthening exercises. Medications that might be utilized include muscle relaxants and anti seizure medications, particularly Carbamazepine. Botox might additionally be used to relieve eye symptoms such as blepharospasm (involuntary blinking of spasm of eyes).  If Botox is not successful in managing eye symptoms, a variety of surgical techniques have been found to be effective. When considering surgery as an option, an important consideration is the risk for malignant hyperthermia, which could lead to adverse outcomes.
Pachyonychia congenita (PC) is a rare inherited condition that primarily affects the nails and skin. The fingernails and toenails may be thickened and abnormally shaped. Affected people can also develop painful calluses and blisters on the soles of their feet and less frequently on the palms of their hands (palmoplantar keratoderma). Additional features include white patches on the tongue and inside of the mouth (leukokeratosis); bumps around the elbows, knees, and waistline (follicular hyperkeratosis); and cysts of various types including steatocystoma. Features may vary among affected people depending on their specific mutation. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17. All forms are inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.
What causes pachyonychia congenita? Pachyonychia congenita (PC) is caused by changes (mutations) in one of five genes: KRT6A, KRT6B, KRT6C, KRT16, and KRT17. These genes provide instructions for making a protein called keratin, which is found in the skin, hair, and nails. Mutations in any of these genes alter the structure of keratin proteins which interferes with their ability to provide strength and resilience to various parts of the body. This leads to the many signs and symptoms associated with pachyonychia congenita. PC is divided into 5 types based on the specific keratin gene involved: PC-K6a, PC-K6b, PC-K6c, PC-K16, and PC-K17.
How is pachyonychia congenita inherited? Pachyonychia congenita (PC) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with PC has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
Is genetic testing available for pachyonychia congenita? Yes, genetic testing is available for the five genes known to cause pachyonychia congenita. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is pachyonychia congenita diagnosed? A diagnosis of pachyonychia congenita (PC) is often suspected based on the presence of characteristic signs and symptoms. In fact, one study found that approximately 97% of people with genetically confirmed PC have toenail thickening, plantar keratoderma (thickening of the skin on the soles of the feet) and plantar pain by age ten. Identification of a change (mutation) in one of the five genes associated with PC confirms the diagnosis.
How might pachyonychia congenita be treated? There is no cure for pachyonychia congenita (PC). Current management is focused on relief of pain and other symptoms; hygienic grooming practices (such as trimming the nails and calluses); and treatment of infections when necessary. Some affected people may also require aids to help with mobility, such as wheelchairs, crutches and/or canes. Pachyonychia Congenita Project offers more detailed information regarding the treatment and management of PC. Please click on the link to access this resource.
What are the signs and symptoms of lipedema? Signs and symptoms of lipedema include enlarged legs extending from the buttocks to the ankles. This enlargement can be painful. The size of the legs are typically out of proportion to the upper body (despite the individuals BMI). The feet are much less involved or spared entirely. In lipedema, the skin does not appear warty, hard (sclerotic), or discolored. Lipedema is not thought to predispose a person to ulcer development. People with lipedema may tend to bruise easily, possibly due to increased fragility of small blood vessel within the fat tissue.
What causes lipedema? The cause of lipedema is unknown. Hormones appear to play a role, especially considering that the condition occurs almost entirely in females and often develops after puberty or other periods of hormone change (e.g., pregnancy, menopause). Although people who are obese may be overrepresented among those with lipedema, persons of normal weight are also commonly affected. As a result, obesity alone is unlikely to be a major determinant of this syndrome. Many people with lipedema have a family history of similarly enlarged legs. At this time the role of genetics in the causation of lipedema is unknown.
How might lipedema be treated? Treatment options for lipedema are limited. A number of therapies that have been tried with minimal success include dieting, diuretics, leg elevation, and compression. Invasive treatments such as lipectomy or liposuction are not recommended because they risk causing damage to the lymphatic system. While, compression therapy may not do much to improve the lipedema, it may help prevent worsening and progression to lymphedema (lipolymphedema).

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.
Spondyloepiphyseal dysplasia (SED) Maroteaux type is a rare skeletal dysplasia that is characterized by short stature beginning in infancy, short, stubby hands and feet, and genu valgum (knock knees). In addition to these physical characteristics, individuals with SED Maroteaux type have some common radiographic findings, including platyspondyly (flattened vertebral bodies in the spine), abnormalities of the pelvis and severe brachydactyly (short fingers and toes). Intelligence is generally normal and there is no clouding of the cornea, which distinguishes SED Maroteaux type from other forms of spondyloepiphyseal dysplasia. SED Maroteaux type is caused by mutations in the TRPV4 gene and is inherited any an autosomal dominant fashion.

Hereditary neuralgic amyotrophy is a type of nervous system disease that affects the brachial plexus. Common signs and symptoms include episodes of severe pain and muscle wasting in one or both shoulders and arms.  Attacks may be spontaneous or triggered (e.g., by exercise, childbirth, surgery, infection etc.).  Secondary complications, such as decreased sensation, abnormal sensations (e.g., numbness and tingling), chronic pain, and impaired movement may develop overtime. Affected members in some families may share additional distinct physical and facial characteristics. Hereditary neuralgic amyotrophy can be caused by mutations in the SEPT9 gene.  It is inherited in an autosomal dominant fashion.

Isodicentric chromosome 15 syndrome is a chromosome abnormality that affects many different parts of the body. As the name suggests, people with this condition have an extra chromosome (called an isodicentric chromosome 15) which is made of two pieces of chromosome 15 that are stuck together end-to-end. Although the severity of the condition and the associated features vary from person to person, common signs and symptoms include poor muscle tone in newborns; developmental delay; mild to severe intellectual disability; delayed or absent speech; behavioral abnormalities; and seizures. Most cases of isodicentric chromosome 15 syndrome occur sporadically in people with no family history of the condition. Treatment is based on the signs and symptoms present in each person.
What are the signs and symptoms of Trismus-pseudocamptodactyly syndrome? While the symptoms of trismus-pseudocamptodactyly syndrome vary from patient to patient, characteristic symptoms include the inability to open the mouth wide (e.g., less than 6 mm, just under 1/4 of an inch) and shortened muscles, including of the hamstrings and calf muscles. As a result of shortened muscles some infants with trismus-pseudocamptodactyly syndrome have closed or clinched fists, club foot, metatarsus adductus, and calcaneovalgus (where the foot bends sharply at the ankle) at birth. Children with this syndrome may crawl on their knuckles. In adulthood the syndrome may cause reduced hand dexterity, however hand limitation does not often interfere with normal function. The most serious complications of the condition occur as a result of the limited mobility of the mouth, including impairment of adequate calorie intake, speech development, dental care, and difficulty with intubation.
