torsion dystonia


Also found in: Wikipedia.

dys·to·ni·a mus·cu·lo·rum de·for·mans

a genetic, environmental, or idiopathic disorder, usually beginning in childhood or adolescence, marked by muscular contractions that distort the spine, limbs, hips, and sometimes the cranial innervated muscles. The abnormal movements are increased by excitement and, at least initially, abolished by sleep. The musculature is hypertonic when in action, hypotonic when at rest. Hereditary forms usually begin with involuntary posturing of the foot or hand (autosomal recessive form [MIM*224500]) or of the neck or trunk (autosomal dominant form [MIM*128100]); both forms may progress to produce contortions of the entire body.

Neurology An AD, possibly also AR condition most common in Jews, onset age 5 to 16 Clinical Gait defects, involuntary contractions and distortion of spine, hands, feet, hips, and eventually neck; lesions typically start in one body region, usually in an arm or leg, and spread to the rest of the body in ±5 yrs; most Pts are wheelchair bound by adulthood; muscles are hypertonic, under voluntary control, hypotonic at rest; IQ unaffected

These cell lines include one disease free pluripotent cell line and 24 others widi individual mutations that give rise to several severe diseases such as cancer (breast cancer, Wilm's tumor and Von Hippel-Lindau syndrome), Huntington's disease, muscular dystrophy (including CMT, FSHD and Myotonic) and cystic fibrosis as well as some rarer genetic diseases such as Trisomy 5, macular dystrophy, incontinentia pigmenti, juvenile retinoschisis, alpha thalassemia and autosomal dominant torsion dystonia.

Early onset torsion dystonia affects approximately 1 in 30,000 - 300,000 persons and, in certain ethnic populations, is prevalent at a frequency of 1 in 10,000.
