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 GeneticsApr 26, 2024The c.769C>G (p.L257V) alteration is located in exon 1 (coding exon 1) of the CNNM1 gene. This alteration results from a C to G substitution at nucleotide position 769, causing the leucine (L) at amino acid position 257 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
