A hexanucleotide repeat modifies expressivity of X‐linked dystonia parkinsonism
12 Apr 2019
Abstract excerpt
OBJECTIVE: repeat within the SVA insertion has been reported as an age-at-onset (AAO) modifier in XDP. Here we investigate the role of this hexanucleotide repeat in modifying expressivity of XDP. METHODS: We genotyped the hexanucleotide repeat in 355 XDP patients and correlated the repeat number (RN) with AAO (n = 295), initial clinical manifestation (n = 294), site of dystonia onset (n = 238), disease severity...
