What are the signs and symptoms of Tay-Sachs disease? The most common form of Tay-Sachs disease begins in infancy. Infants with this disorder typically appear normal until the age of 3 to 6 months, when development slows and muscles used for movement weaken. Affected infants lose motor skills such as turning over, sitting, and crawling. As the disease progresses, infants develop seizures, vision and hearing loss, mental retardation, and paralysis. An eye abnormality called a cherry-red spot, which can be identified with an eye examination, is characteristic of this disorder. Children with this severe form of Tay-Sachs disease usually live only into early childhood. Other forms of Tay-Sachs disease are much rarer. Signs and symptoms can begin in childhood, adolescence, or adulthood and are usually milder than those seen with the infantile form of Tay-Sachs disease. As in the infantile form, mental abilities and coordination are affected. Characteristic features include muscle weakness, loss of muscle coordination (ataxia) and other problems with movement, speech problems, and mental illness. These signs and symptoms vary widely among people with late-onset forms of Tay-Sachs disease. The Human Phenotype Ontology provides the following list of signs and symptoms for Tay-Sachs disease. 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.

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 Tay-Sachs disease? Tay-Sachs disease is caused by mutations in the HEXA gene. The HEXA gene provides instructions for making part of an enzyme called beta-hexosaminidase A, which plays a critical role in the brain and spinal cord. This enzyme is located in lysosomes, which are structures in cells that break down toxic substances and act as recycling centers. Within lysosomes, beta-hexosaminidase A helps break down a fatty substance called GM2 ganglioside. Mutations in the HEXA gene disrupt the activity of beta-hexosaminidase A, which prevents the enzyme from breaking down GM2 ganglioside. As a result, this substance accumulates to toxic levels, particularly in neurons in the brain and spinal cord. Progressive damage caused by the buildup of GM2 ganglioside leads to the destruction of these neurons, which causes the signs and symptoms seen in Tay-Sachs disease,
How might children with Tay-Sachs disease be treated? Although several attempts have been made at purified enzyme replacement therapy for children with Tay-Sachs disease, none has been successful. Cellular infusions and even bone marrow transplantation have been attempted with no evidence of benefit. Because no specific treatment is available for Tay-Sachs disease, treatment is directed at the symptoms and major associated conditions. Treatment is supportive and aimed at providing adequate nutrition and hydration. The airway must be protected. Seizures can be controlled initially with conventional anticonvulsant medications such as benzodiazepines, phenytoins, and/or barbiturates, but the progressive nature of the disease may require alteration of dosage or medication. Infectious diseases should be managed. In advanced disease, good bowel movement should be maintained and severe constipation should be avoided. Good hydration, food additives, stool softeners, laxatives, and other measures should be employed to avoid severe constipation.

Relapsing polychondritis (RP) is a rare condition characterized by recurrent inflammation of cartilage and other tissues throughout the body. Cartilage is a tough but flexible tissue that covers the ends of bones at a joint, and gives shape and support to other parts of the body. Ear involvement is the most common feature, but a variety of other areas of the body may be affected, including the costal (rib) cartilage, eyes, nose, airways, heart, vascular (veins) system, skin, joints, kidney, and nervous system. The signs and symptoms vary from person to person depending on which parts of the body are affected. The exact underlying cause of RP is unknown; however, scientists suspect that it is an autoimmune condition. The primary goals of treatment for people with RP are to relieve present symptoms and to preserve the structure of the affected cartilage.
What causes relapsing polychondritis? The exact underlying cause of relapsing polychondritis (RP) is unknown. However, scientists suspect that it is an autoimmune condition. It it thought that RP occurs when the body's immune system mistakenly attacks its own cartilage and other tissues. In general, autoimmune conditions are complex traits that are associated with the effects of multiple genes in combination with lifestyle and environmental factors. There is also evidence to suggest that some people may be born with a genetic susceptibility to RP. Studies have found that people with RP are roughly twice as likely as those without this condition to carry a certain genetic allele called HLA-DR4. "HLA" stands for human leukocyte antigen, which is an important part of our immune system and plays a role in resistance and predisposition (risk) to disease. However, HLA genes are not solely responsible for specific diseases but instead may simply contribute along with other genetic or environmental factors to disease risk. Thus, many people with HLA-DR4 will never develop RP.
Is relapsing polychondritis inherited? Relapsing polychondritis (RP) is not passed through families in a clear-cut fashion. Most people with relapsing polychondritis do not have affected relatives. Like many other autoimmune conditions, RP is likely a multifactorial condition which is associated with the effects of multiple genes in combination with lifestyle and environmental factors. In general, having a first degree relative (for example a parent, child, or sibling) with an autoimmune condition may increase your personal risk for developing an autoimmune condition. Unfortunately, no specific risk estimates are available for relapsing polychondritis.
How is relapsing polychondritis diagnosed? There are no tests available that are specific for relapsing polychondritis (RP). A diagnosis is, therefore, generally based on the presence of characteristic signs and symptoms. For example, people may be diagnosed as having RP if they have three or more of the following features: Inflammation of the cartilage of both ears Seronegative (negative for rheumatoid factor) polyarthritis (arthritis that involves 5 or more joints simultaneously) Inflammation of the cartilage of the nose Eye inflammation (conjunctivitis, episcleritis, scleritis, and/or uveitis) Inflammation of the cartilage of the airway Vestibular dysfunction (i.e. vertigo, hearing loss, tinnitus) In some cases, a biopsy of affected tissue may be necessary to support the diagnosis.
How might relapsing polychondritis be treated? The primary goals of treatment for people with relapsing polychondritis (RP) are to relieve present symptoms and to preserve the structure of the affected cartilage. The main treatment for RP is corticosteroid therapy with prednisone to decrease the severity, frequency and duration of relapses. Higher doses are generally given during flares, while lower doses can typically be prescribed during periods of remission. Other medications reported to control symptoms include dapsone, colchicine, azathioprine, methotrexate, cyclophosphamide, hydroxychloroquine, cyclosporine and infliximab. People who develop severe heart or respiratory complications may require surgery. More detailed information about the management of RP is available on Medscape Reference's Web site and can be viewed by clicking here.
Hereditary sensory autonomic neuropathy (HSAN) is a group of rare peripheral neuropathies where neurons and/or axons are affected. The major feature of these conditions is the loss of large myelinated and unmyelinated fibers. Myelin is an insulating layer, or sheath that forms around nerves, made up of protein and fatty substances, that allows electrical impulses to transmit along the nerve cells. If myelin is damaged, these impulses slow down. Symptoms of HSAN include diminished sensation of pain and its associated consequences of delayed healing, Charcot arthopathies, infections, osteomyelitis, and amputations. They have been categorized into types one through five, although some children do not fit well into this classification and do not all have altered pain sensation and/or autonomic function.[9873] HSAN type I is the most common form of HSAN. It is caused by a mutation in the SPTLC1 gene and inherited in an autosomal dominant pattern. HSAN type 2 is caused by mutations in the WNK1 gene and inheritance is autosomal recessive . HSAN type 3 (Riley-Day syndrome or familial dysautonomia) is caused by mutations in the IKBKAP gene and inheritance is autosomal recessive. HSAN type 4, also called congenital insensitivity to pain with anhidrosis (CIPA), is caused by mutations in the NTRK1 gene and is an autosomal recessive disorder. HSAN type 5 is caused by mutations in the NGFB gene and inherited in an autosomal recessive manner.
Spondylospinal thoracic dysostosis is an extremely rare skeletal disorder characterized by a short, curved spine and fusion of the spinous processes, short thorax with 'crab-like' configuration of the ribs, underdevelopment of the lungs (pulmonary hypoplasia), severe arthrogryposis and multiple pterygia (webbing of the skin across joints), and underdevelopment of the bones of the mouth. This condition is believed to be inherited in an autosomal recessive manner. It does not appear to be compatible with life.

Persistent genital arousal disorder (PGAD) in men may be considered as the condition of priapism and unwanted ejaculatory fluids being released without any sexual interest. In women there is still no consensus about a formal definition, but some of the experts propose that in women it should be defined as a rare, unwanted, and intrusive sexual dysfunction associated with excessive and unremitting genital arousal and engorgement in the absence of sexual interest. The persistent genital arousal usually does not resolve with orgasm and causes personal distress. Features include excessive excitement or excessive genital (lubrication, swelling, and engorgement) or other somatic responses. Causes may be neurological (central or peripheral involving the pudendal nerve), related to medication, vascular, hormonal, psychological or others.  Diagnosis of the cause is essential for an adequate patient management. The treatment may include avoiding offending medications, using medications that stabilize nerve transmission and/or effect mood, local topical anesthetic agents, ice and hormonal replacement. More recently PGAD has being described as one component of a broader Restless Genital Syndrome if the PGAD was also associated with urinary frequency/urgency and restless leg syndrome.
