Genes affected

CNNM2 (HGNC:103): (cyclin and CBS domain divalent metal cation transport mediator 2) This gene encodes a member of the ancient conserved domain containing protein family. Members of this protein family contain a cyclin box motif and have structural similarity to the cyclins. The encoded protein may play an important role in magnesium homeostasis by mediating the epithelial transport and renal reabsorption of Mg2+. Mutations in this gene are associated with renal hypomagnesemia. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2011]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CNNM2. . Gene score misZ 4.4105 (greater than the threshold 3.09). Trascript score misZ 5.0056 (greater than threshold 3.09). GenCC has associacion of gene with hypomagnesemia, seizures, and intellectual disability 1, familial primary hypomagnesemia with normocalciuria and normocalcemia, renal hypomagnesemia 6.

BP4

Computational evidence support a benign effect (MetaRNN=0.061160624).
