2013-11-1 · Myoclonus-dystonia syndrome (MDS) is a rare movement disorder characterized by mild to moderate dystonia along with 'lightning-like' myoclonic jerks. Epidemiology The estimated prevalence of MDS in Europe is 1/500,000.

The myoclonus jerks typical of M-D most often affect the neck, trunk, and upper limbs. Myoclonus dystonia syndrome (MDS) refers to a group of heterogeneous nondegenerative clinical conditions characterized by the association of myoclonus and dystonia as the only or prominent symptom.

Myoclonus, the principal feature, predominates in the arms and axial muscles and is often responsive to alcohol. We studied 14 patients who had a combination of idiopathic torsion dystonia and myoclonic jerks. In many cases, the same muscles were involved in both the myoclonus and the dystonia. This made observation of the crucial dystonic postures difficult and led to misdiagnosis of other dyskinesias. The jerks usually were brief (50 to 200 msec) and occurred irregularly, often showing cocontraction in 2011-01-11 · Myoclonus dystonia is typically inherited from the father due to maternal genomic imprinting [Grabowski et al.

A genome scan for the family and subsequent fine mapping localized the gene responsible for the disease to the most telomeric 6.73 mega base pairs at the p-terminus of chromosome 16, with a maximum multipoint logarithm-of-odds score of 7.83 and a maximum two-point score of 4.25. Lightning myoclonic jerks with segmental distribution, involving mainly the upper body part with a predominant proximal distribution, alone or combined with dystonia, is reported to be the typical MDS presentation. 7 In our series, distal myoclonus in the upper limbs was also detected in the great majority of patients, and a similar observation has been reported in a large Dutch family.
