Hereditary Sensory and Autonomic Neuropathy Type IE (HSAN-IE) is a rare genetic condition that affects the peripheral nervous system. Individuals with HSAN-IE experience severe sensory and autonomic disturbances, causing a range of symptoms and complications.

The condition is caused by mutations in the IKBKAP gene, which encodes a protein called IκB kinase complex-associated protein (IKAP). These mutations disrupt the normal function of IKAP, leading to the development of HSAN-IE.

HSAN-IE is one of several types of hereditary sensory and autonomic neuropathy, each caused by mutations in different genes. Type IE is particularly rare, with only a few reported cases in the medical literature. Because of its rarity, there is limited information available about the condition, and more research is needed to fully understand its causes and mechanisms.

Patients with HSAN-IE typically experience progressive sensory loss, starting in childhood. They may also have autonomic disturbances, such as excessive sweating or difficulty regulating body temperature. These symptoms can significantly impact daily life and lead to secondary complications, such as ulcerations or infections.

Diagnosis of HSAN-IE is usually based on clinical features and confirmed through genetic testing. There is currently no cure for the condition, and treatment aims to manage symptoms and provide support. Genetic counseling is recommended for individuals with a family history of HSAN-IE, as it follows an autosomal recessive inheritance pattern.

Further research and resources are necessary to better understand HSAN-IE and develop effective treatments. Scientific studies, articles, and additional information can be found in resources such as OMIM, PubMed, and ClinicalTrials.gov. Support and advocacy organizations may also provide valuable support and resources for individuals and families affected by this rare condition.

The last 20 years have seen the cost of medical care increase about 70% faster than the rate of general inflation as measured by the Consumer Price Index (CPI), the Research Division of the Federal Reserve Bank of St. Louis Healthcare inflation dropped to a historical low after 2010 but is again on the rise as of 2018, according to Bloomberg.

Frequency

Hereditary sensory and autonomic neuropathy type IE (HSAN IE) is a rare genetic condition that affects the peripheral nervous system. It is caused by mutations in the PRDM12 gene, which is responsible for regulating the expression of other genes involved in sensory and autonomic function.

The frequency of HSAN IE is not well-known, but it is considered to be a rare disorder. The Nicholson Center for British Columbia Neurological Sciences estimates that the condition affects about 1 in every 600,000 individuals in their region. However, the frequency may vary in different populations.

Additional information on the frequency of HSAN IE can be found in scientific articles and resources such as PubMed, OMIM (Online Mendelian Inheritance in Man), and clinicaltrials.gov. These sources provide information on genetic studies, clinical trials, and other research related to HSAN IE and other hereditary neuropathy disorders.

HSAN IE is associated with severe sensory and autonomic dysfunction. It typically presents in infancy or early childhood with symptoms such as loss of pain sensation, temperature insensitivity, and impaired reflexes. These symptoms can lead to injuries and complications, so early diagnosis and management are important.

Diagnosis of HSAN IE can be confirmed through genetic testing to identify mutations in the PRDM12 gene. Additional testing may include methylation studies and analysis of other genes associated with hereditary neuropathy disorders.

For patients and their families, support and advocacy organizations can provide resources and information on HSAN IE and related conditions. The Nicholson Center, for example, offers support services and educational materials for individuals living with hereditary neuropathy disorders.

Causes

Hereditary sensory and autonomic neuropathy type IE (HSAN IE) is a rare genetic condition that affects the peripheral nervous system and is associated with severe neurological disorders. It is one of several types of hereditary sensory and autonomic neuropathy (HSAN).

HSAN IE is caused by mutations in the IKBKAP gene. These mutations result in a lack of a functional IKBKAP protein, which is essential for the normal development and function of sensory and autonomic nerves.

HSAN IE has an autosomal recessive inheritance pattern, which means that individuals with the condition inherit two copies of the mutated IKBKAP gene, one from each parent. Individuals who inherit only one copy of the mutated gene are usually unaffected carriers of the condition.

Testing for HSAN IE can be done through genetic testing, which can detect mutations in the IKBKAP gene. Genetic testing can be helpful in confirming a diagnosis and determining the specific mutation causing the condition.

Additional information about HSAN IE can be found on resources such as the Hereditary Sensory Autonomic Neuropathies Rare Disease Clinical Research Network (RSNA) and the Online Mendelian Inheritance in Man (OMIM) catalog.

Clinical trials for HSAN IE can be found on ClinicalTrials.gov, which provides information on ongoing research studies and trials related to various diseases and conditions.

Support and advocacy organizations, such as the Hereditary Sensory Autonomic Neuropathies Rare Disease Clinical Research Network, can also provide information and support to individuals and families affected by HSAN IE.
