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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 16, 2024The c.1960C>G (p.R654G) alteration is located in exon 7 (coding exon 7) of the CNNM3 gene. This alteration results from a C to G substitution at nucleotide position 1960, causing the arginine (R) at amino acid position 654 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
