Genes affected
CNNM1 (HGNC:102): (cyclin and CBS domain divalent metal cation transport mediator 1) This gene encodes a member of the ancient conserved domain protein family. The encoded protein may bind copper. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.526G>C (p.G176R) alteration is located in exon 1 (coding exon 1) of the CNNM1 gene. This alteration results from a G to C substitution at nucleotide position 526, causing the glycine (G) at amino acid position 176 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
