Summary: 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.

The novel identified variant in CNNM4 is the first report from the Pakistani population. Sequence analysis of CNNM4 revealed a novel missense variant (c.1220G>T, p.Arg407Leu) in exon-1 encoding cystathionine-beta-synthase (CBS) domain.

Title: Jalili Syndrome: Cross-sectional and Longitudinal Features of Seven Patients With Cone-Rod Dystrophy and Amelogenesis Imperfecta.
Here, we report the 2 first families with Jalili Syndrome in Brazil. Molecular analysis of the first family identified a previously described homozygous mutation (p.Leu324Pro) in exon 1 of CNNM4 gene. In the second family, affected patients demonstrated a compound heterozygous mutation in CNNM4, the p.Leu324Pro and the novel nonsense mutation p.Tyr581*.
Title: Report of two unrelated families with Jalili syndrome and a novel nonsense heterozygous mutation in CNNM4 gene.
Results identified linkage at chromosome 2p14-2q14 and found a homozygous mutation in the CNNM4 gene (p.R605X) causing Jalili syndrome. The truncated CNNM4 protein starting at R605 significantly increased the rate of apoptosis, and significantly increased the interaction between CNNM4 and IQCB1. This mutation may cause Jalili syndrome by a nonsense-mediated decay mechanism, affecting the function of IQCB1 and apoptosis.
Title: Identification of a mutation in CNNM4 by whole exome sequencing in an Amish family and functional link between CNNM4 and IQCB1.
Mutational analysis showed in all three brothers a novel likely pathogenic homozygous missense substitution in exon 1 (c.1076T>C, p.(Leu359Pro)) of CNNM4. Both parents were carriers for the variant.
Title: Co-occurrence of Jalili syndrome and muscular overgrowth.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
