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]

The c.1711G>A (p.G571R) alteration is located in exon 5 (coding exon 5) of the CNNM3 gene. This alteration results from a G to A substitution at nucleotide position 1711, causing the glycine (G) at amino acid position 571 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
