Genes affected

CNNM4 (HGNC:105): (cyclin and CBS domain divalent metal cation transport mediator 4) 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 a role in metal ion transport. Mutations in this gene are associated with Jalili syndrome which consists of cone-rod dystrophy and amelogenesis imperfecta. [provided by RefSeq, Feb 2010]

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a topological_domain Cytoplasmic (size 40) in uniprot entity CNNM4_HUMAN there are 7 pathogenic changes around while only 0 benign (100%) in NM_020184.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.987
• PP5: Variant 2-96761598-C-A is Pathogenic according to our data. Variant chr2-96761598-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 2851.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr2-96761598-C-A is described in Lovd as [Likely_pathogenic].
