As proof of the ongoing new revolution in sequencing technology, over few years, a SINE‐VNTR‐Alu (SVA) retrotransposon insertion in TAF1 has been suggested as the possible molecular cause of X‐linked dystonia‐parkinsonism, with a hexameric repeat expansion within the SVA insertion acting as a genetic modifier of disease expressivity.75, 80. Here, TAF1 is linked to Parkinsonism.
