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]

Ambry Genetics

May 14, 2024

The c.47G>A (p.R16Q) alteration is located in exon 1 (coding exon 1) of the CNNM1 gene. This alteration results from a G to A substitution at nucleotide position 47, causing the arginine (R) at amino acid position 16 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
