▶Whole genome survey of coding SNPs reveals a reproducible pathway determinant of Parkinson diseaseAssociationN=374Srinivasan BS et al.(2009)· Human Mutation
This whole genome association study of 374 Caucasians identified a reproducibly associated axon guidance pathway for Parkinson disease, with rs3770208 (EPHA4, log OR=0.5, p=0.0002) and rs9867325 (EPHA7, log OR=0.61, p=8.65e-05) showing the strongest SNP-level associations. Pathway-level analysis with controlled multiple testing revealed ubiquitin-mediated proteolysis (AUC=0.66, p=0.01), T-cell receptor signaling (AUC=0.59, p=0.04), and axon guidance (AUC=0.60, p=0.05) pathways predictive of PD susceptibility. The axon guidance pathway replicated in an independent PD study.
About HAL
Histidine ammonia-lyase is a cytosolic enzyme catalyzing the first reaction in histidine catabolism, the nonoxidative deamination of L-histidine to trans-urocanic acid. Histidine ammonia-lyase defects cause histidinemia which is characterized by increased histidine and histamine and decreased urocanic acid in body fluids. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]
