Genes affected

CNNM3 (HGNC:104): (cyclin and CBS domain divalent metal cation transport mediator 3) Predicted to enable transmembrane transporter activity. Predicted to be involved in ion transport; magnesium ion homeostasis; and transmembrane transport. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

CNNM3 links:

ANKRD23 (HGNC:24470): (ankyrin repeat domain 23) This gene is a member of the muscle ankyrin repeat protein (MARP) family and encodes a protein with four tandem ankyrin-like repeats. The protein is localized to the nucleus, functioning as a transcriptional regulator. Expression of this protein is induced during recovery following starvation. [provided by RefSeq, Jul 2008]
