Genes affected

CIAO3 (HGNC:14179): (cytosolic iron-sulfur assembly component 3) Predicted to enable 4 iron, 4 sulfur cluster binding activity. Involved in several processes, including iron-sulfur cluster assembly; oxygen homeostasis; and response to hypoxia. Part of CIA complex. [provided by Alliance of Genome Resources, Apr 2022]

CIAO3 links:

HAGHL (HGNC:14177): (hydroxyacylglutathione hydrolase like) Predicted to enable hydroxyacylglutathione hydrolase activity and metal ion binding activity. Predicted to be involved in methylglyoxal catabolic process to D-lactate via S-lactoyl-glutathione. [provided by Alliance of Genome Resources, Apr 2022]
