▶PLD4 as a novel susceptibility gene for systemic sclerosis in a Japanese populationAssociationN=1,141Chikashi Terao et al.(2013)· Arthritis & Rheumatism
This case-control study identified PLD4 as a novel susceptibility gene for systemic sclerosis (SSc) in a Japanese population, with rs2841277 showing significant association (P=0.00017, OR=1.25). The study also confirmed associations between SSc and rs6932056 in TNFAIP3 (P=0.0000095, OR=1.50) and rs2280381 in IRF8 (P=0.0030, OR=1.26). rs2841280 in PLD4 exon 2 was found in strong linkage disequilibrium with rs2841277 and introduces an amino acid change (E27Q).
About GCH1
This gene encodes a member of the GTP cyclohydrolase family. The encoded protein is the first and rate-limiting enzyme in tetrahydrobiopterin (BH4) biosynthesis, catalyzing the conversion of GTP into 7,8-dihydroneopterin triphosphate. BH4 is an essential cofactor required by aromatic amino acid hydroxylases as well as nitric oxide synthases. Mutations in this gene are associated with malignant hyperphenylalaninemia and dopa-responsive dystonia. Several alternatively spliced transcript variants encoding different isoforms have been described; however, not all variants give rise to a functional enzyme. [provided by RefSeq, Jul 2008]
