What are the signs and symptoms of Waardenburg syndrome type 2? In general, Waardenburg syndrome is characterized by varying degrees of hearing loss and changes in skin and hair color (pigmentation). Those with Waardenburg syndrome type 2, do not have a wide space between the inner corners of their eyes or other facial abnormalities. Most have a hearing impairment or are deaf and also have heterochromia of the iris (two different colored eyes). Other features of Waardenburg syndrome, including white forelock, premature graying of the hair, and irregular depigmentation of the skin, are less common in this type. The Human Phenotype Ontology provides the following list of signs and symptoms for Waardenburg syndrome type 2. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Heterochromia iridis 90% Premature graying of hair 90% Sensorineural hearing impairment 90% Hypopigmented skin patches 50% White forelock 50% Abnormality of the kidney 7.5% Abnormality of the pulmonary artery 7.5% Aganglionic megacolon 7.5% Ptosis 7.5% Telecanthus 7.5% Albinism - Autosomal dominant inheritance - Congenital sensorineural hearing impairment - Heterogeneous - Hypoplastic iris stroma - Partial albinism - Synophrys - Underdeveloped nasal alae - Variable expressivity - White eyebrow - White eyelashes - Wide nasal bridge - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. 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.
How is a subtype of Waardenburg syndrome type 2 diagnosed? Subtypes of Waardenburg syndrome type 2 are determined by the suspected genetic cause of the condition in a family.  In some subtypes, the genetic cause is a known gene.  In other subtypes, the general location (locus) of the genetic cause has been identified, but the specific gene is not yet known.  There are five different subtypes:  Type 2A is caused by a change (mutation) in the MITF gene on chromosome 3 Type 2B is associated with a locus on chromosome 1 Type 2C is associated with a locus on chromosome 8 Type 2D is caused by mutations is the SNAI2 gene on chromosome 8 Type 2E is caused by mutations in the SOX10 gene on chromosome 22 Because subtypes are defined by the underlying genetic cause, they are not diagnosed by physical features identified during a physical exam.  Physical features may be used to distinguish between types of Waardenburg syndrome, such as Type 1 or Type 2, but do not help identify a specific subtype.

Wilson disease is a rare inherited disorder that is characterized by the accumulation of copper in the body. Because high levels of copper are toxic to tissues and organs, this buildup can lead to damage of the liver, brain and eyes. Signs and symptoms of Wilson disease include chronic liver disease, central nervous system abnormalities, and psychiatric (mental health-related) disturbances. It is caused by a mutation of the ATP7B gene and is inherited in an autosomal recessive manner. Although there is no cure for Wilson disease, therapies exist that aim to reduce or control the amount of copper that accumulates in the body.
What causes Wilson disease? Wilson disease is caused by changes (mutations) in the ATP7B gene. This gene encodes a protein that plays an important role in the transport of copper from the liver to the rest of the body. It also helps remove excess copper from the body. Mutations in the ATP7B gene prevent this protein from working properly, which can lead to an accumulation of copper in the body. Because high levels of copper are toxic, this buildup can damage tissues and organs and cause the many signs and symptoms of Wilson disease.
Is Wilson disease inherited? Wilson disease is inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.
How might Wilson disease be treated? There is currently no cure for Wilson disease; however, therapies exist that aim to reduce or control the amount of copper that accumulates in the body. Affected people require lifelong treatment, which may include certain medications and/or dietary modifications. If treatment is not effective or if liver failure develops, a liver transplant may be necessary.

Townes-Brocks syndrome is a genetic condition characterized by an obstruction of the anal opening (imperforate anus), abnormally shaped ears, and hand malformations that most often affect the thumbs. Most affected individuals have at least two of these three main features. The condition is caused by mutations in the SALL1 gene which provides instructions for making proteins that are involved in the formation of tissues and organs before birth. It follows an autosomal dominant pattern of inheritance.
What causes Townes-Brocks syndrome? Townes-Brocks syndrome is caused by mutations in the SALL1 gene. This gene is part of a group of genes called the SALL family. These genes provide instructions for making proteins that are involved in the formation of tissues and organs before birth. SALL proteins act as transcription factors, which means they attach (bind) to specific regions of DNA and help control the activity of particular genes. Some mutations in the SALL1 gene lead to the production of an abnormally short version of the SALL1 protein that malfunctions within the cell. Other mutations prevent one copy of the gene in each cell from making any protein. It is unclear how these genetic changes disrupt normal development and cause the  symptoms associated with Townes-Brocks syndrome.
How is Townes-Brocks syndrome diagnosed? Townes-Brocks syndrome is diagnosed clinically based on the presence of the following: Imperforate anus Abnormally shaped ears Typical thumb malformations (preaxial polydactyly, triphalangeal thumbs which have three bones in them, much like the fingers, instead of the normal two, hypoplastic or underdeveloped thumbs) without shortening of the radius (the larger of the two bones in the forearm) SALL1 is the only gene known to be associated with Townes-Brocks syndrome. Detection of a SALL1 mutation confirms the diagnosis. Genetic testing is available on a clinical basis.
Is there treatment for Townes-Brocks syndrome? Treatment is directed towards the specific symptoms, including immediate surgical intervention for imperforate anus; surgery for severe malformations of the hands; routine management of congenital heart defects; hemodialysis and possibly kidney transplantation for end-stage renal disease (ESRD); and early treatment of hearing loss. In addition, regular monitoring of renal function in individuals with and without renal anomalies is suggested.
Cronkhite-Canada syndrome is a rare gastrointestinal disorder characterized by widespread colon polyps, unhealthy looking (dystrophic) nails, hair loss (alopecia), darkening skin (such as on the hands, arms, neck and face), diarrhea, weight loss, stomach pain, and/or excess fluid accumulation in arms and legs (peripheral edema). The cause of the condition is not known. Treatment aims to control symptoms and provide adequate nutrition.

A prosthetic joint infection (PJI) is a rare complication of joint replacement surgery, also known as arthroplasty.  Arthroplasty is done to help relieve pain and restore function in a severely diseased joint, such as a knee, hip or shoulder.  Approximately 0.5 to 1 percent of people with replacement joints develop a PJI.  Infections can occur early in the course of recovery from joint replacement surgery (within the first two months) or much later.  Signs and symptoms of PJI include fever, chills, drainage from the surgical site, and increasing redness, tenderness, swelling and pain of the affected joint.  Prosthetic joint infections are often hard to treat because of the development of a structure called a biofilm within the joint. A biofilm develops when bacteria adhere to the solid surface of the artificial joint. The biofilm can act as a kind of shield to some of the bacteria, making it difficult for the bacteria to be found and destroyed by the body's defenses or by antibiotic medications. An infected joint replacement usually requires surgery to remove the artificial parts and potent antibiotics to kill the bacteria.
A chordoma is a rare tumor that develops from cells of the notochord, a structure that is present in the developing embryo and is important for the development of the spine. The notochord usually disappears before birth, though a few cells may remain embedded in the bones of the spine or at the base of the skull.  Chordomas can occur anywhere along the spine. Approximately half of all chordomas occur at the base of the spine; approximately one third occur at the base of the skull. Chordomas grow slowly, extending gradually into the surrounding bone and soft tissue. The actual symptoms depend on the location of the chordoma. A chordoma at the base of the skull may lead to double vision and headaches. A chordoma that occurs at the base of the spine may cause problems with bladder and bowel function. Chordomas typically occur in adults between the ages of 40 and 70. In many cases, the cause of the chordoma remains unknown. Recent studies have shown that changes in the T gene have been associated with chordoma in a small set of families. In these families an inherited duplication of the T gene is associated with an increased risk of developing chordoma. People with this inherited duplication inherit an increased risk for the condition, not the condition itself.

How might a chordoma be treated? Unfortunately, because chordomas are quite rare, the best treatment for these tumors has yet to be determined.  The current treatment for chordoma of the clivus often begins with surgery (resection) to remove as much of the tumor as possible.  The extent of surgery, or the amount of tumor that may be removed, depends on the location of the tumor and how close it is to critical structures in the brain.  Surgery is followed by radiation therapy to destroy any cancer cells that may remain after surgery.  Several studies have suggested that proton beam radiation or combined proton/photon radiation may be more effect than conventional photon radiation therapy for treating chordomas of the skull base because proton radiation may allow for a greater dose of radiation to be delivered to the tumor without damaging the surrounding normal tissues.  Approximately 60-70% of individuals treated with combined surgery and radiation therapy remained tumor-free for at least five years.

Congenital pulmonary lymphangiectasia is a rare developmental disorder present from birth that affects the lungs. Infants with this condition have abnormally widened lymphatic vessels within the lungs. The lymphatic system, which helps the immune system protect the body against infection and disease, consists of a network of tubular channels that drain a thin watery fluid known as lymph from different areas of the body into the bloodstream. Lymph, which is made up of proteins, fats and certain white blood cells called lymphocytes, accumulates in the tiny spaces between tissue cells. Infants with congenital pulmonary lymphangiectasia often develop severe, potentially life-threatening, respiratory distress shortly after birth. They may also develop cyanosis, a condition caused by low levels of circulating oxygen in the blood which causes the skin to have a bluish tint. The exact cause of the condition is unknown. Congenital pulmonary lymphangiectasia can occur as a primary or secondary disorder. Primary congenital pulmonary lymphangiectasia can occur as an isolated defect within the lungs or as part of a a generalized form of lymphatic vessel malformation that affects the entire body. Secondary congenital pulmonary lymphangiectasia occurs secondary to another condition, often involving the heart.
