Genes affected

OXR1 (HGNC:15822): (oxidation resistance 1) Predicted to enable oxidoreductase activity. Predicted to be involved in response to oxidative stress. Predicted to act upstream of or within several processes, including adult walking behavior; negative regulation of neuron death; and negative regulation of peptidyl-cysteine S-nitrosylation. Predicted to be located in mitochondrion and nucleolus. Predicted to be active in nucleus. Implicated in cerebellar hyplasia/atrophy, epilepsy, and global developmental delay.
