H. Ichinose et al., GTP CYCLOHYDROLASE-I GENE IN HEREDITARY PROGRESSIVE DYSTONIA WITH MARKED DIURNAL FLUCTUATION, Neuroscience letters, 196(1-2), 1995, pp. 5-8
We previously reported four different mutations in the coding region o
f GTP cyclohydrolase I(GCH-I) gene in patients with hereditary progres
sive dystonia with marked diurnal fluctuation (HPD). We found two inde
pendent new mutations (leucine 79 proline and a deletion in exon 4) in
patients with HPD. We also found four families of HPD without any mut
ations in the coding region of GCH-I gene.
