XDP TAF1

X-linked dystonia-parkinsonism (XDP) associated with antisense insertion of a SINE-VNTR-Alu (SVA)-type retrotransposon within an intron of TAF1. Clinical features include focal and generalised dystonia, parkinsonism, cognitive dysfunction. XX individuals who are heterozygous carriers usually do not develop the full syndrome, although some patients have non-progressive focal dystonia with parkinsonism. Disease severity is associated with number of hexanucleotide repeats within the SVA. (Adapted)¹.

Prevalence

Philippines overall 0.34:100,000. Panay Islands 5.24:100,000. Capiz province 18.9:100,000. To date, all known cases to date are of Filipino descent¹.

Age of Onset Details

Average age of onset for XDP is 39.7 years in males, 52 years in females, range 12-79 years. ~99% of cases are male^2,1,3.
