| Strumpell-Marie disease | <rheumatology> A polyarthritis involving the spine, which is characterised by progressive, painful stiffening of the joints and ligaments. It almost exclusively affects young men. Interestingly the disease seems to be associated with HLA B27, those with this histocompatability antigen are 300 times more likely to get the disease, 90% of sufferers have HLA B27 (18 Nov 1997) |

| Foix-Cavany-Marie syndrome | <syndrome> Constellation of facio-pharyngo-glosso-masticatory diplegia with automatic voluntary dissociation without associated dementia or forced laughing or crying usually caused by bilateral large artery infarcts of the opercular cortex. (05 Mar 2000) |
| acute ataxia | Generalised ataxia of abrupt onset, most often caused by drug intoxications, poisonings, or vestibular neuronitis. (05 Mar 2000) |
| ataxia | <neurology> Failure of muscular coordination, irregularity of muscular action. Origin: Gr. Taxis = order (16 Dec 1997) |
| ataxia cordis | <cardiology> A condition where there is disorganised electrical conduction in the atria, resulting in ineffective pumping of blood into the ventricle. Acronym: AF (02 Jan 1998) |

| ataxia-telangiectasia | <neurology, oncology> An intriguing autosomal recessive disorder in which a single defective gene produces myriad and protean effects, presents with cerebellar ataxia, telangiectasias in the eyes and skin, immune deficiency and autoimmune phenomena, propensity for lymphoid and other malignancies, excessive sensitivity to ionising radiation, increased serum alpha-fetoprotein concentrations and a tendency for chromosome breakage and translocation. A syndrome characterised by choreoathetosis beginning in childhood, progressive cerebellar ataxia, telangiectasis of conjunctiva and skin, slowly progressive mental deterioration and increasing cerebellar degeneration. There is evidence that heterozygotes show an increased susceptibility to malignancy as well, with breast cancer often cited. The gene was localised by linkage studies to chromosome 11q22-23, and recently cloned, revealing it to be homologous to the PI-3 kinase family so that prenatal diagnosis by RFLP analysis is possible. Other related genes are suspected to exist. Diagnosis in affected patients is made on clinical grounds, by detection of high concentrations of alpha-fetoprotein, and by a specialised cell culture assay for radiosensitivity and atypical radioresistant DNA synthesis. These cell culture methods are also used for prenatal diagnosis. A characteristic autopsy feature of ataxia-telangiectasia is the presence of empty basket cells in the cerebellum which results from degeneration of the previously contained Purkinje cells. Inheritance: autosomal recessive. (16 Dec 1998) |
