Ataxia telangiectasia is a rare genetic disease that causes multiple symptoms related to poor co-ordination, abnormal blood vessels and a compromised immune system. There is no treatment for ataxia telangiectasia and management focuses on monitoring and treating the specific risks posed by the condition, such as lung infections. In The C Word, Emily Lawson has inherited more than two copies of. Ataxia-telangiectasia is chiefly characterized by progressive cerebellar ataxia, conjunctival and cutaneous telangiectasias, severe immune deficiencies, recurrent sinopulmonary infections, and a markedly increased risk of malignancy
Ataxia-Telangiectasia or Louis Bar Syndrome is usually diagnosed based on the characteristic features ataxia, telangiectasia, abnormal ocular movements and impairment of speech. This diagnosis can be confirmed by laboratory screening. With observation of all the clinical signs and symptoms the diagnosis can be made relatively easily Other articles where Ataxia-telangiectasia is discussed: nervous system disease: Neurocutaneous syndromes: Ataxia-telangiectasia (Louis-Bar syndrome) results in cerebellar incoordination and choreic movements, overgrowth of blood vessels on the conjunctiva (eye membranes), and disorders of the immune system

All serum-α-fetoprotein concentrations in patients. Test description. This test analyzes the ATM gene, which is associated with ataxia-telangiectasia (A-T). Individuals with pathogenic variants in both copies of the ATM gene can develop A-T, a condition characterized by childhood-onset progressive cerebellar ataxia, oculomotor apraxia, choreoathetosis, telangiectasias of the conjunctivae, immunodeficiency, and increased risk for malignancy. Ataxia telangiectasia (AT) is a rare, progressive, neurodegenerative childhood disease that affects the nervous system and other body systems. The hallmarks of AT are ataxia (lack of muscle control) and other movement disorders, and telangiectasias (tiny, red spider veins), which appear in the corners of the eyes or on the surface of the ears and cheeks after the onset of ataxia Symptomatic: Ataxia telangiectasia is a genetic condition with no cure. As such, therapy is directed at treating consequences of this disease. For example, it is best to avoid excess radiation (excess x-rays, ct scans) be wary of any signs of infection (due to immune compromise) and be vigilant about signs of malignancy (weight loss, night sweats, etc.) Ataxia telangiectasia.Hirsutism on the lower legs and ecchymoses secondary to ataxia and numerous falls.. Ataxia telangiectasia is a progressive neurodegenerative genetic disease characterized by cerebellar ataxia (incoordination and lack of balance), ocular telangiectasia (red eyes due to widening of small blood vessels in the conjunctiva), immune defects, and a predisposition to malignancy

Definition of the disease: Ataxia telangiectasia (A-T) is an autosomal recessive disorder primarily characterized by cerebellar degeneration, telangiectasia, immunodeficiency, cancer. Ataxia telangiectasia (AT): Also known as Louis-Bar Syndrome, AT is an inherited condition. It typically develops in babies or young children. A common symptom of this type of ataxia is the appearance of enlarged (dilated) blood vessels known as telangiectasias in the eyes and on the skin of the face Ataxia telangiectasia (A-T) results from inactivation of the ATM protein kinase. DNA-damage signaling is a prime function of this kinase, although other roles have been ascribed to ATM. Identifying the primary ATM function(s) for tissue homeostasis is key to understanding how these functions contribute to the prevention of A-T-related pathology. In this regard, because A-T is primarily a. Ataxia-telangiectasia is an autosomal-recessive primary immunodeficiency disorder that involves combined humoral and cellular deficiencies. Estimated incidence is 1 in 20,000 to 100,000 births. Ataxia-telangiectasia is caused by mutations in the gene that encodes ataxia-telangiectasia-mutated (ATM) protein
