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.29C>A (p.P10Q) alteration is located in exon 1 (coding exon 1) of the CNNM4 gene. This alteration results from a C to A substitution at nucleotide position 29, causing the proline (P) at amino acid position 10 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
