Hereditary sensory and autonomic neuropathy Hereditary sensory and autonomic neuropathy (HSAN) or hereditary sensory neuropathy (HSN) is a condition used to describe any of the types of this disease which inhibit sensation.enes related to Hereditary sensory and autonomic neuropathy Type 3 : Mutations in the IKBKAP gene cause familial dysautonomia. The IKBKAP gene provides instructions for making a protein called IKK complex-associated protein (IKAP). This protein is found in a variety of cells throughout the body, including brain cells.

Small Fiber Sensory Neuropathy Small Fiber Sensory Neuropathy. Small fiber sensory neuropathy (SFSN) is a disorder in which only the small sensory cutaneous nerves are affected. The majority of patients experience sensory disturbances that start in the feet and progress upwards. These patients have what is called a length-dependent SFSN.ymptoms. The symptoms of small fiber sensory neuropathy are primarily sensory in nature and include unusual sensations such as pins-and-needles, pricks, tingling and numbness. Some patients may experience burning pain or coldness and electric shock-like brief painful sensations.

Giant axonal neuropathy Giant axonal neuropathy usually appears in infancy or early childhood, and is progressive. Early signs of the disorder often present in the peripheral nervous system, causing individuals with this disorder to have problems walking. Later, normal sensation, coordination, strength, and reflexes become affected.iant axonal neuropathy has an autosomal recessive pattern of inheritance. Giant axonal neuropathy results from mutations in the GAN gene, which codes for the protein gigaxonin. This alters the shape of the protein, changing how it interacts with other proteins when organizing the structure of the neuron.

Are you sure your patient has Pancreatitis? What are the typical findings for this disease? Hereditary (4%) Hereditary pancreatitis is autosomal dominant condition with incomplete penetrance (about 80%) and is related to mutations in the cationic trypsinogen gene (PRSS1 gene mutations). Gain of function mutations in this gene cause premature activation of trypsinogen to trypsin.

- All types of Charcot-Marie-Tooth disease (CMT) cause degeneration of the peripheral nerves, leading to muscle weakness and some loss of sensation in the arms, legs, hands, and feet. These symptoms often first appear during adolescence or early adulthood, but can develop later in life, as well.t is named after the three doctors who described it in 1886: Jean Martin Charcot and Pierre Marie in Paris, and Howard Henry Tooth in Cambridge, England. Charcot-Marie-Tooth disease is also sometimes referred to as hereditary motor and sensory neuropathy (HMSN) or peroneal muscular atrophy.

- Neurofibromatosis, also known as NF, is a genetically inherited disorder of the nervous system (brain and spinal cord) which mainly affects the development of nerve (neural) cell tissues, causing tumors (neurofibromas) to develop on nerves, and may cause other abnormalities.eurofibromatosis is the most common genetic neurological disorder that is caused by a single gene. According to the National Health Service (NHS), UK, Nf1 affects approximately 1 in every 2,500 newborns. Although the odds seem small, Nf1 is classed as a common genetic disorder.

- Hereditary sensory and autonomic neuropathy type IE (HSAN IE) is a disorder that affects the nervous system. Affected individuals have a gradual loss of intellectual function (dementia), typically beginning in their thirties.weating is a function of the autonomic nervous system, which also controls involuntary body functions such as heart rate, digestion, and breathing. These other autonomic functions are unaffected in people with HSAN IE.

Autonomic Neuropathy Paraneoplastic autonomic neuropathy; Hereditary causes: eg, Anderson-Fabry disease, Tangier disease, multiple endocrine neoplasia (type 2b). Idiopathic causes: chronic idiopathic anhidrosis. Epidemiology. In general, these can occur in men and women at any age, but the epidemiology will depend on the particular cause. Some causes are very rare. However, one of the most common causes of autonomic neuropathy is likely to be diabetes mellitus. Progressive autonomic failure usually becomes apparent in the sixth decade of life. Typically it manifests with genitourinary symptoms and orthostatic hypotension but without somatic symptoms.

Autonomic neuropathy By Mayo Clinic Staff. Autonomic neuropathy occurs when the nerves that control involuntary bodily functions are damaged. This may affect blood pressure, temperature control, digestion, bladder function and even sexual function. The nerve damage interferes with the messages sent between the brain and other organs and areas of the autonomic nervous system, such as the heart, blood vessels and sweat glands. While diabetes is generally the most common cause of autonomic neuropathy, other health conditions — even an infection — may be to blame. Some medications also may cause nerve damage. Symptoms and treatment will vary based on which nerves are damaged.

Overview Charcot (shahr-KOH)-Marie-Tooth disease is a group of inherited disorders that cause nerve damage. This damage is mostly in your arms and legs (peripheral nerves). Charcot-Marie-Tooth is also called hereditary motor and sensory neuropathy. Charcot-Marie-Tooth disease results in smaller, weaker muscles. You may also experience loss of sensation and muscle contractions, and difficulty walking.

Neuromyelitis optica AQP4+ NMO is currently considered an autoimmune disease (autoimmune astrocytopathy, or autoimmune astrocytic channelopathy) in which a person's own immune system attacks the astrocytes of the optic nerves and spinal cord. The cause of the AQP4- variants is unknown.pinal cord lesions lead to varying degrees of weakness or paralysis in the legs or arms, loss of sensation (including blindness), and/or bladder and bowel dysfunction. Devic's disease is now studied along a collection of similar diseases called Neuromyelitis optica spectrum diseases.
