“…However, these results have not been replicated in Serbian, Chinese, Italian, or Caucasian dystonia cohorts 58,7375. To date, two meta-analyses have evaluated the effects of rs6265 variant on dystonia 75,76. The most recent reports a statistically significant overall effect of the AA genotype on the development of idiopathic dystonia 76.…”

“…Additionally, higher frequency of bilateral postural arm tremor in CD patients with the BDNF Met66Met variant than inVal66Met and Val66Val carriers has also been observed 72.

“…Dabei erbrachte die eine Studie ein erhöhtes Risiko bei den Trägern der Variante für das Auftreten einer Dystonie (ca. 800 Patienten vs. 1000 Kontrollen) [79], welches sich in der anderen, vergleichbar großen Studie [80] nicht zeigte. Einen hypothesenfreien Ansatz stellen die genomweiten Assoziationsstudien (Genome-Wide Association Studies [GWAS]) dar, die Varianten in ARSG (Arylsulfatase) und NALCN (Natriumkanal) als mögliche Risikofaktoren für Musiker-Dystonie [81] bzw.…”
