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]

The c.40C>G (p.P14A) alteration is located in exon 1 (coding exon 1) of the CNNM4 gene. This alteration results from a C to G substitution at nucleotide position 40, causing the proline (P) at amino acid position 14 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
