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]

ACMG classification

Our verdict: Likely_benign. The variant received -6 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.29).
• BS2: High AC in GnomAdExome4 at 7 AD gene.
