26400349 Exonic deletion in the GCH1 gene only accounted for the etiology in a small percentage of patients with sporadic dopa-responsive dystonia in our Han Chinese cohort.
26215833 The risk of orofacial clefts is associated with variants of the GCH1 gene related to BH4 metabolism.
25783971 No association was seen between the pain protective GCH-1 haplotype and the development of hypersensitivity following injury. An increase in baseline pain thresholds was seen between visits in protective haplotype carriers who sensitized to injury.
25634433 identified a novel missense variant, c.5A > G, p.(Glu2Gly), within the GCH1 gene in affected family members displaying a range of phenotypes; variant is pathogenic in studied family and may underlie Parkinson's disease and Dopa-responsive dystonia
25599448 Postherniotomy pain and related activity impairment was associated with functional variations in GCH1 (and COMT).
25369080 Five polymorphisms forming two haplotype blocks within the GTP cyclohydrolase 1 gene are associated with endothelial dysfunction and oxidative stress.
25270546 This is the first study to report changes in the expression of GTP Cyclohydrolase I of this gene in schizophrenia.
25192508 DYT5 is caused by heterozygous mutations of the GCH1 gene, located on 14q22.1-q22.2[review]
25119902 A novel GCH1 gene frameshifing mutation is aooociated with the dopa-responsive dystonia in a Chinese family.
24993959 Rare GCH1 variants are associated with an increased risk for Parkinson's disease.
